Heat transfer enhancement in single micro channel using micro fins

Abstract

A three dimensional numerical simulation of developing laminar and turbulent flow in a micro channel is carried out. Constant wall heat flux is applied at the bottom of the substrate and the remaining surfaces are insulated. Water is used at the working fluid which enters the channel inlet with a slug velocity profile. Micro fins are considered along the channel length at different locations. When fluid flows past any The term "enhanced" has get to be exceptionally vital for the business with advancing time. Due to progressed manufacturing techniques moderately complex geometry can be fabricated very effortlessly. Here, Different Reynolds number will be taken to differentiated between the heat transfer between the laminar and the turbulent stream. A 3-dimensional channel without fin was taken as the reference and after taking a fin in the channel the heat transfer improvement is compared with a simple microchannel. A wide range of materials with diverse thermal conductivity for the substrate as well as for the fin was taken to get distinctive solid by fluid conductivity ratio (ksf) which play an important role in heat transfer process. Thermal performance of microchannel with single and multiple hurdles studied.
