Projects in the fluid dynamics area involve low Reynolds number hydrodynamics, rheology of complex fluids, kinetic theory, two-phase flow, flow through porous media, and surfactant behavior in organic-aqueous systems. Projects in the heat transfer area include change-of-phase processes (evaporation, condensation, and boiling), microelectronics cooling, Marangoni instabilities and its effect on fluid flow and the performance of change of phase devices, such as heat pipes. Research is in progress on simultaneous heat and mass transfer in porous media, effects of surface roughness and chemical heterogeneity on particle interactions with surfaces, separation efficiency of membrane systems, ion and electron transport through dielectric materials, and crystal growth phenomena.
