Abstract
Thermal performance of micro-hole cellular structure using water as a cooling fluid was investigated through CFD and then numerical results were validated with the experimental results. The minimum base temperature for the micro-hole cellular structure was found to be 29.7 degrees C and 32.3 degrees C numerically and experimentally, respectively, with volumetric flow rate of 0.000034 m(3)/s (2 Lpm) at a heating power of 345 W. Numerical values of the base temperature are in close agreement with experimental results with an error of 8.75%. Previously, the base temperatures of heat sinks using alumina nanofluid with 1% of volumetric concentration and water with volumetric flow rate of 0.000017 m(3)/4 (1 Lpm) have been reported to be 43.9 degrees C and 40.5 degrees C, respectively.
