Investigation of obstacle effect to improve conjugate heat transfer in backward facing step channel using fast simulation of incompressible flow
, Article Heat and Mass Transfer/Waerme- und Stoffuebertragung ; 2017 , Pages 1-16 ; 09477411 (ISSN) ; Moazezi, A ; Sharif University of Technology
Abstract
The current study investigates the conjugate heat transfer characteristics for laminar flow in backward facing step channel. All of the channel walls are insulated except the lower thick wall under a constant temperature. The upper wall includes a insulated obstacle perpendicular to flow direction. The effect of obstacle height and location on the fluid flow and heat transfer are numerically explored for the Reynolds number in the range of 10 ≤ Re ≤ 300. Incompressible Navier-Stokes and thermal energy equations are solved simultaneously in fluid region by the upwind compact finite difference scheme based on flux-difference splitting in conjunction with artificial compressibility method.
