Driven cavity flow

The following examples concern flow in and over cavities.

In the cavity, the flow separates and produces complex flow patterns (`Taylor-Goertler vortices'!), oscillating in space and time if the Reynolds number is sufficiently large. The complexity of the problem depends on the:

• speed on the walls ("on the top")
• viscosity
• size and geometry of the cavity

A systematic variation of these different configurations is part of the following flow situations.

• Lid Driven Cavity (length 3) at medium Reynolds number
