Heat transfer Heat exchanger Microchannel Parallel flow Counter flow Numerical Heat -- Transmission Organized by School of Mechatronic Engineering (UniMAP) & co-organized by The Institution of Engineering Malaysia (IEM), 11th - 13th October 2009 at Batu Feringhi, Penang, Malaysia. Thermal behaviors of parallel and counter flow micro-heat exchanger are investigated numerically, with emphasis on the role of wall resistance and entry effects. The influence of different parameters, such as, thermal resistance (R), Knudsen number (Kn), effectiveness (ε ) and number of transfer units (NTU) on the heat transfer characteristics are investigated. It is found that the temperature jump at the walls increase with increasing thermal resistance (R) and Knudsen number (Kn). On the other hand, the NTU increases with decreasing R and Kn. It is also found that the effect of R on ε is insignificant for parallel and counter flow. Furthermore, for counter flow microchannel heat exchangers, that the heat conduction in the separating wall and the entrance regionplays a significant role in the overall heat transfer process and thus thermally fully developed flow may not exist over a large section of the heat exchanger. 2009-11-08T13:16:16Z 2009-11-08T13:16:16Z 2009-10-11 Working Paper p.5C 1 - 5C 10 978-967-5415-07-4 http://hdl.handle.net/123456789/7225 en Proceedings of International Conference on Applications and Design in Mechanical Engineering 2009 (iCADME 2009) Universiti Malaysia Perlis
