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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
