Numerical Forced Convection Heat Transfer, Fluid Flow and Entropy Generation Analyses of Al2O3- Water Nanofluid in Elliptical Channels

This study investigates a three-dimensional elliptical microchannel heat sink for dissipation in laminar forced convection. The seeks to improve thermal performance and overcome overheating associated with excessive temperature commonly experienced heat-generating equipment, which is beyond the usually specified by manufacturer. objective of evaluate transfer, fluid flow, entropy generation characteristics Al2O3-water nanofluid an cooling channel. numerical analysis investigated on structure experiencing constant volumetric generation. parameters considered are Reynolds number 100 ≤ Re 500, nanoparticle concentration ϕ, from 0% 4% channel aspect ratio Ar 1 3. impacts these maximum temperature, transfer coefficient, friction factor, reported. demonstrates that enhanced at different ratios, concentrations, Reynold numbers. results showed as concentration, ratio, (Re) increase, total decrease. As increases = 200 ɸ 3%, decrease up 62% while coefficient 78% factor increase less than 2% ratio. However, not sensitive coolant.
