Abstract

In this study, by using water as a cooling fluid, the three-dimensional fluid flow and heat transfer in a rectangular micro-channel are analyzed numerically. The microchannel have a depth of 180 μm and a width of 57 μm, and length of 10 mm. A numerical analysis is simulated using a Gambit 2.4.6 and Fluent 6.1 version. The results carefully validated by comparing the data with the other available experiment data. In terms of velocity profiles, flow Reynolds number affects the length of the flow developing region. For the higher value of Reynold number of 1500, fully developing region may not be achieved. It is also found that the temperature rises along the flow directional in the solid and fluid region can be approximately linear for the microchannel investigation. Temperature is high at the channel top wall rather than channel bottom wall with the deviation of 0.51%. At near channel inlet, the Nusselt number much more higher values and vary around the channel periphery, approaching 5 average Nusselt number.
