Abstract :

Heat transfer characteristics for enclosed micro cavities had been studied. The rarefaction effect; (i.e., Knudsen number (Kn) effect) on the Nusselt number is illustrated. Also, the effect of Raleigh number (Ra) on Nusselt number (Nu) is illustrated as well. In this study, a numerical code is used for the simulations that cover the slip regime. Also, a correlation is being derived for the Nusselt number (Nu) as a function of Prandtl number (Pr), Raleigh number (Ra) and Knudsen number (Kn).

Biography :

Wael G Al-Kouz has completed his PhD in 2009 from Worcester Polytechnic Institute (WPI) where he had worked on micro/nano flows simulations using the unstructured three dimensional direct simulation Monte Carlo method (U3DSMC) and Postdoctoral studies from University of Manitoba. After that, he had worked extensively in the industry where he had concentrated on the renewable energy and HVAC systems. He is a registered professional engineer in the province of Manitoba and an ASHRAE member. Currently, he is working as an Assistant Professor of mechanical engineering at the German Jordanian University (GJU) and the owner/general manager for Espire-Jordan Company, which is specialized in the renewable energy/energy efficient solutions.
