1. Leaky Lid Driven Cavity Flow

The classical problem of the closed cavity driven by the motion of a leaky lid has been used rather extensively as a validation test case by many authors (see Ghia et al, 1982 for details). In this problem a unit velocity is specified along the entire top surface and zero velocity on the other surfaces as shown in Figure 4
