WebIn this section we will use the Multiple Reference Frame method, which is used for the stationary flow solution computation. To simulate the rotation, the real movement of the mesh is substituted by momentum sources in the stationary cells – we add the so called Coriolis term. We need to choose the rotating zone, where we simulate the rotation. WebRotation using OpenFOAM In this chapter we will show two different approaches to rotation modeling in OpenFOAM. We will build our own test case and try following methods: MRF (Multiple Reference Frame) Solid Body Motion Subsections Test case: mixerVessel Test case description Test case set-up Test case: Multiphase Mixer Preprocessing …
