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

t1 stator 1

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