Air-side heat transfer enhancement in compact heat exchangers: Compact heat exchangers are used extensively in the automobile, aerospace, and Heating, Ventilation & Air-Conditioning (HVAC) industries. The performance of heat exchangers is limited by the air-side heat transfer coefficient. The research aims at understanding the performance of different augmentation surfaces through the use of high fidelity computer simulations.
Multi-physics computations in micron scale (10-6 m) devices: Micron scale devices have important applications in medicine, aerospace, and other emerging industries. Flow of gases and liquids in micron scale devices exhibit a range of phenomena not encountered in large scale devices. Our research is developing computational tools for simulating electro-osmotic and electrophoretic effects for lab-on-a-chip applications.
Terascale Computing in Computational Fluid Dynamics: Unprecedented advances have been made in computer hardware with the ability to put together hundreds or thousands of processors in geographically distributed clusters on a GRID with high bandwidth networks. Our research aims at developing computational fluid dynamics simulation software, which can take advantage of these distributed facilities for computations, data archiving, visualization and analysis.
Enhanced prediction techniques for internal cooling of turbine blades: Turbine blades are subjected to very high temperatures and have to be cooled internally by passing cooling air through roughened serpentine channels. Our research is evaluating and developing enhanced prediction techniques based on large-scale time-accurate simulations of the highly turbulent flow and heat transfer under the effects of rotation and buoyancy forces.
