I have published several such models. I doubt the lid driven cavity is a particularly useful geometry for real world applications. These are most often used to visualize and test computational models and methods of solving various partial differential equations.
Thank you Dear Dr. Dudley J Benton
These are the applications of computational methods. But I want to know the real life applications of lid driven cavity.
As I explained, I don't know that there are any real life application of the lid driven cavity problem. Most real life applications have much more complex geometry and boundary conditions.
It's like flow over a flat plate... used to illustrate many developments and derivations, including boundary layers, beginning with Prandtl. The nearest thing in the real world to a flat plate is perhaps an airfoil or propeller blade.
Thanks Dr. Dudley J Benton
Would you tell me please the difference between moving wall and slipping wall ?
In the lid driven cavity (with origially stagnant fluid) a slip-wall would not induce any flow within the cavity, while die to viscous entrainment a flow is induced for by the lid wall.
For a slip wall any velocity tangential to the wall is allowed at the slip wall. This velocity is derermined by the flow in the cavity. In a lid flow cavity the fluid velocity at wall is equal to the wall velocity (in a continuum approximation for a viscous fluid).
Would you tell me please what condition I use in Comsol Multiphysics for slipping wall?
