FLUID FLOW IN A SQUARE CAVITY WITH MOVING HORIZONTAL WALLS - A SIMULATION BY MARKER AND CELL (MAC) METHOD

Abstract

The Marker and Cell (MAC) method with uniform, Cartesian staggered grid has been developed to solve the non-dimensional 2D Navier-Stokes equations. The developed numerical code is validated with the published benchmark problem and compared with the numerical simulation for lid driven cavity flow. Next, the numerical code has been applied for uniformly moving horizontal walls for various Reynolds numbers (Re = 100, 400 and 1000). The formation of vertices with in the cavity strongly depends on Reynolds number.
