Multiphase Flow and Heat Transfer

Fluids undergoing phase change (such as evaporation, condensation) are of great importance in many engineering problems. These include cooling, fuel vaporization, power generation systems, and many industrial processes that rely on evaporation and/or condensation, such as coatings, crystal growth in semiconductors, polymer processing, magnetic storage devices, and more. As technologies advance and push the limits of traditional thermal management, however, a more thorough understanding of the coupled fluid and thermal transport phenomena is needed. Of particular interest in current UW research are the behavior of evaporating films under non-stationary conditions and the phase-change and heat transfer behavior associated with cryogenic liquid propellants. Also of interest are the non-equilibrium processes that can result from very rapid evaporation processes.
