Application Cases

2D Cavity flow problem

This is a 2D CFD simulation of the well known lid-driven cavity flow problem. The reference solution has been taken from Marchi et. al. (2009), The following applications of Kratos are used:

• MeshingApplication
• ExternalSolversApplication
• FluidDynamicsApplication

Case Specification

A one meter square-shaped domain is considered. The fluid parameters are set such that the Reynolds number is 100, thus:

• Density (ρ): 1.0 Kg/m³
• Kinematic viscosity (ν): 0.01 m²/s

The boundary conditions are:

• Bottom, left and right boundaries: No-slip
• Top boundary: v = [1.0,0.0] m/s
• Top left corner: v = [0.0,0.0] m/s
• Top right corner: v = [1.0,0.0] m/s
• Bottom left corner: p = 0.0 Pa
