The figure shows a “square cavity flow”. In this flow the cavity is filled with a fluid and the lid of the cavity moves with a constant velocity, while the other walls stay stationary. This causes a recirculation in the cavity. The flow is supposed 2 dimensional incompressible, with Umax=1.0 m/s constant. The lengths of the sides of the cavity, L, are all equivalent to 1.0 m

Run the program for the following Reynolds numbers: 10, 100, 500 and 1000. The Reynolds number is defined by Re = Umax.L/ν, where ν is the fluid kinematic viscosity, which in this case, differs to produce the dissimilar Reynolds numbers. The boundary conditions are: uab = ubc = ucd = vab= vbc= vcd = vad = 0 and uad = Umax

Employ a staggered grid of at least 15x15 cells, and the SIMPLE algorithm for your solutions.

Plot both velocity and pressure distributions for all Reynolds numbers.
