Library case Y619: Inlet flux scaling: swirling flow in a chamber.

This example shows how to use grid-free features of PLANT for calculation of scaling factors resulting from the presentation of circle inlets on Cartesian coordinate system.

The problem is to introduce the correct mass and momentum in-fluxes for the concentric inlets at the east wall of lower part of 3D rectangular chamber with a swirl in annular secondary flow inlet.

It is supposed that MARK of unity value marks the primary inlet area, while MARK=2 is used to specify secondary inlet cells.

2. What PLANT puts into GROUND.
   

3. Results.
   

• Marker distribution specifying the inlet cells.
  
• Velocity vectors at inlet plane.
  
• Velocity vectors at symmetry plane.
