[CFD] Multiple Reference Frame (MRF) Approach for Turbomachinery

A brief introduction to Multiple Reference Frame (MRF) approach, which is used to simulate the motion of rotors/impellers and blades. The following topics are covered: 1) 10:56 What additional source terms are added in the Single Reference Frame (SRF) approach? 3) 17:34 What additional source terms are added in the Multiple Reference Frame (MRF) approach? 4) 19:22 How is the face volume flux modified in the MRF approach? Frozen Rotor and Mixing Plane approaches will be considered in a separate video. ================================== Derivation of the SRF and MRF equations: 1) OpenFOAM Wiki Derivation of the SRF and MRF equations ============================================ Want to learn more? ============================================ Grab a copy of my CFD Fundamentals Course (for beginners):
