WebThe two-equation Realizable k-ε eddy viscosity turbulence model has been used to simulate the turbulent flow field on a 2D plane (i.e., on a 5-degree sector of the experimental domain), because Realizable k-ε more accurately predicts the spreading rate of both planar and round jets and presents the best proficiency in comparison with all versions of the k … WebMixing Plane Model (MPM) 2. Sliding Mesh Model (SMM) Here we shall discuss more about only the MRF model. Multiple Reference Frame (MRF) model: The MRF model is the simplest of the two approaches for multiple zones. It is a steady-state approximation in which individual cell zones move at different rotational and/or translational speeds.
