چکیده
Real-life multiphase flows exhibit a number of complex and visually appealing behaviors, involving bubbling, wetting, splashing, glugging. However, most state-of-the-art simulation techniques in graphics can only demonstrate limited range flow phenomena, due to their inability handle the real water-air density ratio large amount numerical viscosity introduced its coupling with interface. Recently, kinetic-based methods have achieved success simulating ratios high Reynolds numbers efficiently; but memory overhead, stability, numerically-intensive treatment immersed solids remain enduring obstacles adoption movie productions. In this paper, we propose new kinetic solver couple incompressible Navier-Stokes equations conservative phase-field equation which remedies these major practical hurdles. The resulting two-phase immiscible fluid is shown be efficient massively-parallel nature GPU implementation, as well very versatile reliable because enhanced stability ratios, numbers, solid boundaries. We highlight advantages our through various challenging results that capture intricate turbulent air-water interaction, including comparisons previous work footage.

An Efficient Multigrid-FEM Method for the Simulation of Liquid-Solid Two Phase Flows
An efficient multigrid-FEM method for the detailed simulation of solid-liquid two phase flows with large number of moving particles is presented. An explicit fictitious boundary method based on a FEM background grid which covers the whole computational domain and can be chosen independently from the particles of arbitrary shape, size and number is used to deal with the interactions between the ...
