OpenFOAM and Rotating Machinery: Relative Velocity

In turbomachinery theory relative velocity is defined as w = c – u where u is circumferential velocity and c is absolute velocity at specified point. The relative velocity w is very important for evaulation of flow in or around rotating bodies. When using SRFSimpleFoam, Urel is automatically added to to resulting fields. With others (SimpleFoam with […]
