Computing Complex Multiphase Flows on Massively Parallel Computers

Talk: Keynote Abstract: We present an approach for direct numerical simulations of multiphase flows on several to over 100 000 parallel processes. The code we call BLUE is based on a dual Front Tracking/Level Set approach and accurately handles capillary forces and complex interface dynamics including changes of topology resulting from breakup. Modules for flow, mass and heat transport are designed with particular attention to parallel memory management. We demonstrate solutions in a variety of challenging multiphase applications in microfluidics, free surface and interfacial flows as well as interactions of multiphase flows with solid structures. We also describe the architecture and discuss the parallel performance of the code.Non UBCUnreviewedAuthor affiliation: CNRSOthe
