Heat transfer and viscous work are involved, and can be modeled by using the Total Energy heat transfer model and enabling the Viscous Work Term option in CFX-Pre.

The industry-standard Shear Stress Transport model is the recommended choice for these cases. When using the Shear Stress Transport model, ensure a resolution of the boundary layer of more than 10 points. For details, see The k-omega and SST Models in the CFX-Solver Modeling Guide.

A common boundary condition configuration is to specify the total pressure and total temperature at the inlet and either the mass flow, exit corrected mass flow, or static pressure at the outlet, depending on the flow condition. Other configurations are also commonly used.

A good estimate of the timestep is within the region to , where is the angular velocity of the rotating domain in radians per second. Selecting an automatic timestep will result in a timestep of .

The second-order high-resolution advection scheme is generally recommended.
