Research Areas

Our fundamental work is in Fluid Mechanics and Convective Heat Transfer areas. Our applied work is especially motivated by engineering phenomena arising in  Thermal Management of Electronic Systems and Renewable and Alternative Energy Systems. Our current research areas are:

NSF Industry/University Cooperative Research Center on Energy Efficient Electronic Systems (E3S)

Droplet Impingement and Spray Cooling

Mini - Microchannel Heat Exchangers and Cold Plates

Flow and Convective Heat Transfer in Jets and Complex Flows

Energy Technology

Experimental Techniques
