Multi-physics/multi-scale processes occur in a wide range of science and engineering applications, such as automotive engines, CVD reactors and rocket engines. Such processes are characterized by the close interaction of several physical phenomena. Furthermore, such processes occur over widely varying spatial and temporal scales, hence posing significant computational challenges. Development of appropriate physical models and numerical tools are necessary for the numerical simulation of such processes. This talk presents a few case studies in the areas of supercritical fluids, scramjet engines, and combustion kinetics. Issues with regard to model development and computational effort are also discussed.

Dr. Shashi Aithal obtained his M.S. in Nuclear Engineering and Ph.D. in Mechanical Engineering from The Ohio State University in 1993 and 1997, respectively. His research interests lie in the area of multi-disciplinary scientific computing. Over the last 10 years he has worked on a wide variety of multi-physics/multi-scale problems such as semiconductor plasmas, hypersonic flows in scramjets and supercritical fluids in liquid rocket engines.
