 Notes
Abstract: A computer program was developed that can be used to study oscillating flows past a two-dimensional step in which the oscillation is induced by two oscillating pistons, one on each side of the step. The computer program was based on the conservation equation of mass momentum, and total energy valid for unsteady, laminar flow of an ideal gas. The computer program generated numerical solutions to the conservation equations by using the time-split method of MacCormack. To demonstrate the usefulness of the computer program for studying oscillating flows past a two-dimensional step, the computer program was used to to study the velocity field of three different types of flows past a step. The three types of flows studied were 1. Steady flows past a step. 2. Oscillating flows past a step with the pistons oscillating in phase. 3. Oscillating flows past a step with pistons oscillating out of phase. It is noted that the two types of oscillating flows investigated here have never been studied by previous investigators. The velocity fields generated by the computer program for these three types of flows are presented in graphical form, to illustrate the flow patterns. Analysis of the flow patterns indicated that the computer program is useful for studying oscillating flows past a two-dimensional step.
