Abstract
Results for laminar two-dimensional backward facing step flow case with and without the presence of an adiabatic square cylinder obstacle is presented in this work. Location of the detachment point on the lower wall, as well as velocity profiles were obtained and compared between the cases. The goal is to identify the influence of the obstacle upon the flow behavior. A developed Fortran code that employs the UNIFAES method to discretize the advective and viscous fluxes of the Navier-Stoke equations is utilized in the simulations. The momentum equations are integrated after the solution of a Poisson pressure equation. The study utilizes a staggered uniform regular mesh. The results shows the effects of the obstacle presence upon the flow pattern.
