Areas of Interest

Ali Koşar's research interests lie in heat and fluid flow in micro heat sinks, micro/nano scale cooling, cavitation, boiling heat transfer, and MEMS (Microelectromechanical Systems). He has been conducting pioneering research on single-phase and boiling heat transfer, single-phase and two-phase pressure drop, critical heat flux (CHF), and cavitation in MEMS-based pin fin, second generation microchannel heat sinks. The results of his research have generated many papers on micro heat sinks in some prestigious journals like Journal of Heat Transfer and International Journal of Heat Transfer. Moreover, he also has some conference papers. RESEARCH INTERESTS Two-phase flow, Boiling Heat Transfer, Convective heat transfer, Critical Heat Flux, Electronic cooling, Microsystems, Nano/micro scale Heat Transfer, Minuatorization of heat sinks, Microfluidics
