Notes

Summary:
Summary: Direct-reading tables and charts are presented for determining the drag or thrust coefficients from wake-survey measurements in the subsonic speed range. For flows wherin no energy is added, the point drag coefficient is shown to be an explicit function of the stream Mach number M lower case o, the static-pressure coefficient at the wake station P₁, and the total-pressure-loss coefficient deltaH/qsubscript o, where deltaH is the total-pressure loss and qsubscript o is the stream dynamic pressure. Values of the point drag coefficient are tabulated for a wide range of values of these parameters. Inasmuch as the tabulated coefficients (either drag or thrust) represent the point values, which are independent of the integration of the wake, the charts or tables in the form presented are general in application. For flows wherein energy is added, such as flows behind propellers or heated radiators, an additional parameter, which is a function of the stagnation-temperature rise, must be considered. Values of the point drag coefficient that include the effects of the addition of energy are tabulated.

NUMERICAL EVALUATION OF THE WAKE-SURVEY EQUATIONS

FOR SUBSONIC FLOW INCLUDING THE EFFECT

OF ENERGY ADDITION

By Donald D. Baals and Mary J. Mourhess


SUDMJ.ARY


Direct-reading tables ard charts are presented for
determining the drag or thrust coefficients from wake-
survey merrasurements in the subsonic speed range. For
fl.ovs wherein no energy is added, the point drag coef-
ficient is shown to be an explicit function of the stream
MachT number Mo, the static-pressure coefficient at the
wake station Pl, and the total-pressure-loss coeffi-
cienc AH/q where AH is the total-pressure loss
and qo is the stream dynamic pressure. Values of the
point drag coefficient are tabulated for a wide range
of values of these parameters. Inasmuch as the tabulated
coefficients (either drag or thrust) represent the point
values, which are independent of the integration of the
wake, the charts or tables in the form presented are
general in application.

For flows wherein energy is added, such as flows
behind propellers or heated radiators, an additional
parwaeter, which is a function of the stagnation-
temperature rise, must be considered. Values of the
point drag coefficient that include the effects of the
addition of energy are tabulated.


INTRODUCE T ION


In the field of aeronautical research,wake pressure
surveys have been used increasingly for determining
profile drag, internal drag, jet thrust, and related
factors. The evaluation of the drag or thrust from

pressure surveys is based on the solution of the momentum
equation. For high-speed flows, in which the air must be
considered compressible, the evaluation of the drag or
thrust must include the variation in the density of the
air; this variation in the density necessarily complicates
the solution of the momentum equation. For flows wherein
energy has been added, the density variation is of
importance even for the low-speed conditions.

Because a large number of pressure readings are
usually required to make a complete wake survey, it is
essential that solutions of the wake-survey equations
for all types of flow be presented in a form to permit
rapid and accurate computation. Various simplifying
techniques have been developed for evaluation of the
drag coefficient from wake pressure measurements by
means of charts or tables, but these methods have required
excessive interpolation or computation due to the form
of the parameters employed. When simplifying assumptions
as to the shape of the wake profile and the constancy of
the static pressure across the wake are made, integration
techniques may be combined with the solution of the wake-
survey equations (references 1 and 2) to reduce greatly
the required computation. This method has been found
useful in determining the section profile-drag coefficients
of airfoils; however, such a method is not general in
application and is limited by the original assumptions
of uniform static pressure and a definite wake profile.

The method found to be most generally applicable at
the Langley 8-foot high-speed tunnel consists in the
point-by-point evaluation of the drag coefficient by
means of direct-reading charts with the final integra-
tion performed in a separate step. Facility of evalu-
ation of the drag coefficient is provided in that the
point-by-point values can be determined from simple
charts. The charts require no assumptions as to wake
profiles or pressure gradients. The flexibility required
for application to both two- and three-dimensional flows
is provided by performing the integration in a separate
step. In this report the solution of the wake equations
has been developed for both isoenergic flows (constant
total energy) and flows wherein energy has been added;
thus the equations are generally applicable to flows
behind airfoils, propellers, and radiators. The funda-
mental principles may be applied to the determination of
the thrust from jet units; however, consideration must be
given to the change in the value of the ratio of specific
heats and the momentum of the fuel.

DISCUSSION OF THEORY AND METHODS

Fuindamental Relations

The detailed solutions of the basic wake-survey
equations for flows with and without the addition of
energy have been presented in reference 3. A theoretical
analysis of the basic assumptions required for the solu-
tion of the wake-survey equations for isoenergic flows
has been presented in reference 4.

The basic form of the drag equation as derived from
the momentum relation is

With the usual assumption that the total pressure at sta-
tion 2 (where p2 = Po) is equal to the total pressure
at station 1, the drag coefficient can be evaluated as
indicated in the appendix. The numerical solution of
equation (1), however, is difficult and requires excessive
computation for direct use.
For convenience in presenting and discussing the
solution of equation (1) the point drag coefficient is
defined as

Negative values of the point drag coefficient indicate
that the system is producing thrust.

Isoenergic Flows

Isoenergic flows are found over aerodynamic bodies
or through internal-flow systems vhen no appreciable
change in stagnation temperature occurs. An analysis
of the terms constituting the point drag coefficient for
isoenergic flows indicates that the point drag coeffi-
cient is an explicit function of the free-stream Mach
number Mo, the static-pressure coefficient in the
wake Pl, and the total-pressure-loss coefficient AH/qo.
The pressure coefficients used are merely an expression
of the measured data in coefficient form. Because the
values of these parameters can be easily determined from
the test data, their use provides a convenient and direct
method for evaluation of the point drag coefficient. An
explicit expression for the point drag coefficient in
terms of the parameters Mo, P1, and AH/qo is com-
plicated; but the coefficient can be easily determined
by usual methods for given values of these parameters
(see appendix).

Values of the point drag coefficient for a wide
range of values of pressure coefficients P1 and AH/qo
and for given values of stream Mach number Mo are
presented in table I. The range of total-pressure-loss
coefficients has been extended into the negative region
(which indicates a total-pressure increase) to permit
evaluation under conditions of low energy input approaching
isoenergic flow. The application of table I to flows
wherein energy has been added will be discussed in a
later section. A large range of positive values of P1
has been included to permit computation of internal duct
flows for which the static-pressure coefficient may
approach unity.

Other forms of the parameters and other methods of
presentation than those used in table I may be more
suitable for certain applications. Instead of Mach

respectively. The two parameters and -H

have an advantage when they can be determined directly
from the measured wake and stream pressures. Tables and
charts of the point drag coefficient for isoenergic flow
in terms of these two parameters are presented in refer-
ence 5 with charts and tables for rapid evaluation by an
approximate method.


Flows Wherein Energy Is Added


The fundamental relations expressed in equation (1)
are correct for the evaluation of the drag or thrust
coefficient for flows wherein energy has been added, such
as flows through radiators or propellers. The evaluation
of the density ratio p2/Po, however, involves an added
parameter that is a function of the energy input. The
evaluation of the density ratio p2/Po as developed in
appendix B of reference 5 becomes

In order to determine the drag coefficient from equa-
tion (1) for flow conditions wherein energy has been

added, an additional parameter must be deter-

mined; this parameter is designated K.

An inspection of the terms constituting the point
drag coefficient (equation(2)) indicates that the

L-0 can be expressed as a function of Mo,

o
the point drag coefficient can therefore be determined
independently. Values of the two parts of equation (2)
required to evaluate the point drag coefficient for flows
wherein energy has been added are presented in tables II
and III.

The value of the energy parameter K can be com-
puted directly for flow conditions where the energy
input and mass flow are measurable' and are uniform across
the survey plane. Such a condition might be attained
for flow through an efficient radiator installation. For
flow conditions as found behind a propeller, however,
where the energy input and elemental mass flow are not
uniform and are difficult to measure, an evaluation of
the energy parameter can better be made by experimental
methods.

The energy equation from the free stream to the wake
station becomes

where the prime refers to the stagnation temperature,
The energy parameter becomes, then, merely the ratio of
the stagnation-temperature rise to the absolute stream

NACA ARR No. L5H27


Inasmuch as the stagnation-temperature differ-
once T1' Tor is small and must be measured accurately,
stagnation-temperature thermocouples or resistance
thermometers may be connected and calibrated to read
the stagnation-temperature difference directly. The
free-stream stagnation-temperature reference may be
obtained by installing one of the temperature-measuring
elements outside the wake. The determination of the
absolute free-stream static temperature does not require
great accuracy; therefore, conventional methods may be
used.


USE OF TABLES AND CHARTS


The values presented in tables I to III for evalua-
tion of the point drag coefficient are difficult to apply
directly because interpolation is required. The tabulated
values have therefore been plotted in the form of direct-
reading charts.

Isoenergic Flows

Examples of the types of plot found useful for
evaluation of the point drag coefficient for isoenergic
flow are presented in figure 2 for Mo = 0.20 and 0.70,
respectively. A representative cross plot of the tabular
data of table I is presented in figure 3. It should be
pointed out that the scale of the plots of point drag
coefficient presented in this report is too small for
accurate work. These plots have been included, however,
to indicate the general form of the curves and to provide
a basis for more accurate large-scale plots based on the
original tabular data.

The charts in their present form are especially
applicable for use in high-speed wind tunnels, where
tests are usually run at fixed values of stream Mach
number, and the value of the static-pressure and
total-pressure-loss coefficients can be determined
directly from the pressure records and wind-tunnel
calibration. For use at values of stream M1ach numbers
different from those tabulated, the chart for the
nearest tabulated Mach number may be used with but small
error percent). For greater accuracy at the inter-
mediate Mach numbers a linear interpolation may be
assumed (fig. 5).








HiACA ARR No. L5H27


The presentation of the tabulated results may be
changed from that used in figure 2 to fit various con-
ditions. For example, the ratio -a-d may be clotted
AH/q
instead of cd' in order to attain greater accuracy on
a small-scale plot. For many tests the wake static-
pressure coefficient remains essentially constant with
changes in Mo; therefore the point drag coefficient
may be plotted against AH/q0 for a range of values
of Mo at given values of P1. The use of the tabulated
data in this form may be applicable to flight tests.


Flows Wherein Energy Is Added

In figure 4 are presented representative plots of
tables II and III for evaluating the point drag coeffi-
cient for flows wherein energy is added. This figure
shows that an increase in stagnation temperature of the
order of 10 F (K = 0.002) can produce a significant
effect on the evaluation of the drag coefficient at low
values of AH/qo. For many cases,however, the energy
effect may be considered negligible as, for example,
the flow behind a lightly loaded propeller and the
tabulated results for isoenergic flow (table I) may be
used directly. A comparison of the numerical result for
the experimental value of K with that for K = 0
indicates the magnitude of the energy effect and which
form of the equations should be used. The isoenergic
values of cd' presented in table I correspond to the
values of cd' for K = 0 presented in tables II and III.
Because the solutions of the equations for isoenergic
flow can be determined from table I directly in one
step, table I should be used whenever the energy effect
can be neglected.

It should be pointed out that for flows wherein
energy is added, certain combinations of the parameters
AH
Mo, P1, *-, and K specify supersonic flow in the
wake. For such flows the measurement of the wake pres-
sures is subject to corrections that are dependent on
the intensity of the shock at the local supersonic speed.
No attempt has been made in this report to evaluate
these shock corrections to the measured pressures.







IJACA ARR No. L5H27


Integration Techniques

The evaluation of the total-drag coefficient involves
the integration of the point-Irag-coefficient profile.
Inasmuch as the evaluation of cd' is independent of
the integration process, great flexibility in the appli-
cation of the proposed wake-survey techniques to various
types of flow can be attained. The flows behind air-
foils, within internal-flow systems, or through pro-
pellers may therefore be calculated by similar methods
that vary only in the integration technique employed.
The wake profile and the manner in which the wake is
surveyed will determine the optimum type of integration.

With the values of the point drag coefficient deter-
mined from the charts or tables presented in this report,
the value of the total-drag coefficient becomes


CD = 1 d' dA1
wake

where AR. is the reference area upon which CD is to
be based. The integration technique employed should be
determined from considerations of expediency and the
accuracy of integration desired.

For two-dimensional flows behind airfoils the
airfoil-section drag coefficient becomes


Cd = cd' dy
w fake

where the integral represents the area under the cd'-
curve when expressed in the same units as the chord c.

the value of the point drag coefficient cd' of 0.1964.

For the use of the equations in the foregoing form,
some initial value of one of the pressures must be
