Investigation of heat transfer in wavy and dual wavy micro-channel heat sink using alumina nanoparticles

Thermal management is crucial for the proper functioning of a system whether it in electronics, process industry, automobile, and renewable devices. Micro-channel heat exchanger has proved to be efficient ejection from systems due high transfer surface volume ratio. This study focuses on evaluating cooling performance straight, wavy, dual wavy Micro-Channel Heat Exchanger by modelling model ANSYS Fluent. The incompressible fluid considered laminar regime using alumina-based nanofluids with 1%, 3%, 6% concentration. solution computed selecting SIMPLE pressure-velocity coupling scheme second-order momentum energy discretization. Nusselt number, pressure drop, base temperature, Performance Factor (TPF) are used as parameters comparing at Reynolds number range 100–900. For transfer, well increased number. It observed that channels compared straight channel improved convective formation secondary vortices curved section. Dual flat wall showed highest increase more than double when equal nano particles addition all channels, average both improvement 8% 0% concentration channel. reduced heater temperature 10 °C 9 A maximum 2.2 achieved configuration nanoparticles. • effect geometry nanoparticles concentrations friction factor microchannel. conventional uniform considering volume. optimum identified drop. was an 6 100 900
