Abstract
In this work we investigate numerically the influence of square obstacles on the flow of an incompressible Newtonian fluid inside a two-dimensional ventilated cavity. Our objective is to analyze the flow configurations and to examine the changes in the pressure drop between the inlet and the outlet ports as a function of the size of the obstacles, their position inside the cavity and of the Reynolds number. For this purpose, we use a second order projection method coupled with a finite difference discretization scheme to evolve the Navier-Stokes equations and to keep the velocity field solenoidal. The flow in a ventilated cavity is important in many technical applications, such as microelectronic cooling and in the process of ventilation inside buildings.
