Vortex Formation in Lid-driven Cavity with Disturbance Block

Authors: Reza Maddahian, Hassan Basirat Tabrizi, Maysam Saidi


In this paper, numerical simulations are performed to investigate the effect of disturbance block on flow field of the classical square lid-driven cavity. Attentions are focused on vortex formation and studying the effect of block position on its structure. Corner vortices are different upon block position and new vortices are produced because of the block. Finite volume method is used to solve Navier-Stokes equations and PISO algorithm is employed for the linkage of velocity and pressure. Verification and grid independency of results are reported. Stream lines are sketched to visualize vortex structure in different block positions.

Keywords: finite volume method, lid-driven cavity, Disturbance Block
