Geometry description

  • In this test case we assume an idealized model of mixer in two dimensions. The test case will be later extended to three dimensions and modified.
  • Basic test case geometry is following:

openfoam tutorial mixer vessel 2
openfoam tutorial mixer vessel 3

Figure: OpenFOAM tutorial mixerVessel2D. Geometry view.

  • The test case is two-dimensional
  • In the center of the domain there is a rotor with four blades
  • Peripheral wall is not moving
  • Steady-state solution of turbulent flow of incompressible fluid
  • For rotation Multiple Reference Frame (MRF) method is used
  • MRF adds source term (acceleration) to velocity (momentum) equations
  • Source term is used on volume cells cellZone
