High Performance Simulation of Multiphase Flow
Prof Stephane Zaleski (Sorbonne Université,CNRS,Institut Jean le Rond ∂’Alembert, FR)
Droplets, bubbles and interfaces offer fascinating physical and mathematical problems and are a key part of the microscopic modeling of multiphase flow in cavitation and other contexts. The talk will describe how to address these problems numerically, using tools such as the Volume of Fluid method with exactly mass and momentum conserving numerical methods and accurate, well balanced capillary forces. The issues arising from the upscaling of simulations to the most extreme HPC environments will also be discussed.
