Autodesk Simulation CFD provides the ability to analyze rotating devices surrounded by a static (non-rotating) frame of reference. By physically rotating the device and the region immediately surrounding it, this capability offers greater flexibility for analyzing rotating machinery. Examples include pumps, fans, blowers, and turbines. Centrifugal, axial, and mixed configurations are supported, as are devices with multiple rotating components (such as the pump and turbine in an automotive torque converter).
This functionality provides the ability to analyze the flow within the blade passages of a rotating device., and also allows study of the interaction between rotating and non-rotating geometry. A classic example is the interaction between the rotor and the stator in an axial compressor or turbine. Another example is the influence of a volute cutwater (tongue) on the exit flow from a centrifugal pump impeller.
