A NUMERICAL STUDY OF FORCED CONVECTIVE FLOW IN MICROCHANNELS HEAT SINKS WITH PERIODIC EXPANSION-CONSTRICTION CROSS SECTION

Öz:

This paper aims to study numerically the laminar convective heat transfer of ionized water flow insiderectangular heat sinks with periodic expansion-constriction cross-section; each heat sink consists of parallelmicrochannels system with 4 mm wide and 0.1 mm deep in constant cross-section segment. Two-dimensionallaminar numerical simulations, based on Navier-Stoks equations and energy equation, are obtained under the sameboundary conditions for different microchannels. In this study, the heat transfer and pressure drop insidemicrochannels with cross-section (cylindrical grooves and triangular cavities) are compared with that of simplesmooth microchannel at Reynolds number ranging from 150-1500; an increase in pressure drop of 44% for allmicrochannels is observed with Reynolds number increasing. The obtained results indicate an enhancement inNusselt number for all microchannels at all Reynolds number values with a maximum enhancement of 36%, theseameliorated thermal parameters attribute to enhance the heat transfer efficiency of proposed microchannels. Whichimprove the effect of periodic expansion-constriction cross-section on the heat transfer performance formicroelectromechanical systems (MEMS) cooling phenomena.
