Transient runs takes into account interactions, vane and wake effects, interferences between the vanes /profiles, unsteadiness of flow and strong interaction along the interface between rotor and stator.nnFrozen rotor holds true if and only if you can move along that rotating interface and you the flow is not changing:this is very ideal but an engineering way as the time to solution is lower than running unsteady!.nnSo the main flow is actually is unsteady but a steady approximation can sometimes bring us to the same level of accuracy but at less efforts:Sometimes!n
