Multi-region approach

In general, this methodology allows working with any number of regions. This computational model consists of three parts (regions). We consider following regions:

 

  • rotor is rotational part of the model, fluid is flowing over rotating wheel
  • stator is static part of the model, fluid is flowing through
  • solid is solid part of the model, no flow, only temperature equation is solved, can be switched off to run just fluid flow simulation with adiabatic walls

During simulation, each region is computed individually and each region communicates with other regions through special boundary conditions.
