Numerical simulations of two dimensional laminar mixed convection flow over backward facing step with different inlet geometries in a duct is investigated by using finite volume method. The wall down downstream of the step is kept at a temperature of 330K and constant heat flux of 500W/m2, while the other walls that form the other side of the duct are thermally insulated. Ethylene glycol is used as working fluid and three types of barrier which are triangular, parallelogram and semicircle are carried out to compare with a simple entrance of backward facing step. The Reynolds number was in the range of 50Re200 and fluid temperature is 300K at the inlet of the channel. Parallelogram inlet has the highest average velocity in all sections and highest average Nusselt number over downstream. Also triangular inlet has the highest shear stress all over the downstream of the duct and cause to make a highest skin friction coefficient.

ABSTRACTMixed convection flow of second grade fluid bounded by a permeable stretching surface is discussed. Soret and Dufour effects are also present. Series solutions for the resulting problems are made using homotopy analysis method (HAM). Analysis has been carried out for the effects of embedded parameters on the velocity, temperature and concentration fields. Numerical values of Nusselt and Sherwood numbers are computed and discussed.
