Numerical study of thermal performance with nanoparticles and grooves in Microchannel

The fluid flow and heat transfer characteristics for a laminar flow in a two-dimensional grooved microchannel has been numerically investigated. A suitable range of parameters such as Reynolds numbers, volume fraction, and groove offset are studied. The characteristics are investigated for various offsets in the grooved microchannel. The results specify an increase in heat transfer performance with increase in volume fraction, Reynolds number, and offset between upper and lower grooves. The offset 1 (δx=1) is found to be the most efficient groove arrangement with a high Nusselt number maintaining the least pressure drop coefficient.
