Abstract: |
A new hybrid Eulerian-Lagrangian numerical method, based on a volume particle meshing of the Eulerian calculation
grid, is proposed for solving interface tracking in free surface flows. Two approaches are designed, called Volume
Of Fluid Sub-Mesh method (VOF-SM Vincent (2010)) and Level Set Sub-Mesh (LS-SM). The advantage of the
methods is that they do not involve any numerical diffusion, insure mass conservation on a Lagrangian point of view
and can be coupled to sub-mesh physical models, as is done in Eulerian-Lagrangian dispersed models. The methods
are first presented: they are linked to a Lagrangian advection of the VOF or distance function brought by markers
seeded in the fluid domain, a redistribution of particles on the Eulerian grid is sometimes involved and finally, the
Eulerian concentrations or level set result from the projection of the volume and scalar informations handled by the
virtual particles. The particle velocities are interpolated from the Eulerian velocity field. The VOF-SM and LS-SM
methods are validated on several scalar interface tracking problems (advection and shearing of a circle, curvilinear
shearing of a circle in a converging-diverging pipe) and are compared to existing schemes within the literature. A
third order of convergence in space is observed, with relative errors one to two orders of magnitude lower than the
best methods of the literature. The VOF-SM ans LS-SM are finally coupled to a Navier-Stokes solver and applied
to the simulation of free surface flows, such as the three-dimensional dam-break flow in a tank. Compared to the
simulations and experiment presented in Kleefsman (2005), the VOF-SM and LS-SM methods have demonstrated
that the water heights and pressure magnitudes are perfectly recovered. In addition, the Lagrangian character of the
sub-mesh approaches allow to capture details of the free surface at a scale smaller than the local grid size. |

General Note: |
The International Conference on Multiphase Flow (ICMF) first was held in Tsukuba, Japan in 1991 and the second ICMF took place in Kyoto, Japan in 1995. During this conference, it was decided to establish an International Governing Board which oversees the major aspects of the conference and makes decisions about future conference locations. Due to the great importance of the field, it was furthermore decided to hold the conference every three years successively in Asia including Australia, Europe including Africa, Russia and the Near East and America. Hence, ICMF 1998 was held in Lyon, France, ICMF 2001 in New Orleans, USA, ICMF 2004 in Yokohama, Japan, and ICMF 2007 in Leipzig, Germany. ICMF-2010 is devoted to all aspects of Multiphase Flow. Researchers from all over the world gathered in order to introduce their recent advances in the field and thereby promote the exchange of new ideas, results and techniques. The conference is a key event in Multiphase Flow and supports the advancement of science in this very important field. The major research topics relevant for the conference are as follows: Bio-Fluid Dynamics; Boiling; Bubbly Flows; Cavitation; Colloidal and Suspension Dynamics; Collision, Agglomeration and Breakup; Computational Techniques for Multiphase Flows; Droplet Flows; Environmental and Geophysical Flows; Experimental Methods for Multiphase Flows; Fluidized and Circulating Fluidized Beds; Fluid Structure Interactions; Granular Media; Industrial Applications; Instabilities; Interfacial Flows; Micro and Nano-Scale Multiphase Flows; Microgravity in Two-Phase Flow; Multiphase Flows with Heat and Mass Transfer; Non-Newtonian Multiphase Flows; Particle-Laden Flows; Particle, Bubble and Drop Dynamics; Reactive Multiphase Flows |
