Direct numerical simulation of multiphase flow is of interest for characterizing a wide range of physical phenomena and industrial processes. The current state of the field will be reviewed and our new developments will be presented. Our new methods significantly extend the range of multiphase flow phenomena that can be represented accurately with direct numerical simulation. The main features of the new method are preserving the topological integrity of interfaces during advection while maintaining mass conservation as well as the implementation of second order interfacial jump-conditions. These features are combined with accurate, robust and scalable multigrid solvers on adaptive Cartesian grids to address large-scale physical problems. The potential application of our new solver will be discussed for a range of outstanding problems in multiphase flow in porous media, flow stability and mixing.


Amir Riaz received his Masterís degree in Aerospace Engineering from the University of Southern California in 2001 and his doctorate in Mechanical Engineering from the University of California Santa Barbara in 2003. He was subsequently a physical sciences research associate at Stanford University in the department of Energy Resources Engineering. He is currently an Assistant Professor of Mechanical Engineering at the University of Maryland, with a research program focusing on numerical simulations of multiphase flows and flows in porous media, as well as carbon dioxide sequestration and enhanced oil recovery.
