Research Foci

Multiphase Materials Processing

André Bénard, Michigan State University, Group Leader

The Multiphase Materials Processing Group will develop improved theoretical models and computational methods for predicting the microstructure of complex fluids in confined flows and free jets. The results will support the development and use of advanced materials reinforced, for example, by nanoscale fibers and particles (clays). The goal of this group is to develop computational tools capable of evaluating innovative strategies for manufacturing multiphase composite materials.

Multiphase Transport Phenomena in Porous Media

George Chase, The University of Akron, Group Leader

The Porous Media Group aims to develop improved models and computational methods for quantifying multiphase flows and heat transfer through natural and synthetic porous media. The results will support the further development of high efficiency filters for diesel exhaust, soot removal from engine oils, gas phase coalescers, oil/water separators, and oil & gas reservoir simulations. In addition, the improved computational tools will be used to evaluate natural convection heat transfer processes within fuel cells and around partially buried pipelines on the ocean floor.

Multiphase Mixing, Reactions and Turbulence

Farhad Jaberi, Michigan State University

The Multiphase Mixing, Reactions, and Turbulence Group will develop improved computational methods for tracking the motion of an interface between two immiscible phases. The results will support the analysis of multiphase processes such as liquid jet breakup, environmental mixing of oil and water, coalescence of liquid droplets on fibers, the stability of liquid/gas interfaces encountered in liquid molding, fuel sprays, interfacial reactions, crystallization, hydrate and wax formation in oil-gas-water pipelines, and fluid-fluid separators.

The research group will also focus on developing improved methods to predict the mean field velocity and the mean field pressure distributions for multiphase flows with strong streamline curvature. Research results will support the analysis of hydrocyclone separators, mixing of liquid and gases in furnace tubes, and liquid/gas sprays.

Multiphase Separations

Ram Mohan, The University of Tulsa, Group Leader

The Multiphase Separations Group will develop computational methods for predicting the separation of two-phase and three-phase fluids (esp. oil/water and oil/water/gas) and re-suspension of solids in three phase fluids. The results will support the evaluation of subsea and surface oil-water-gas pipelines, separator designs, and the strategic placement and performance of sand separators.
