百度一下这个官方算例：Modeling of Film Separation at Backward Facing Step 1. Introduction Backward facing step is a widely used benchmark problem to evaluate the performance of turbulence models for the prediction of separated flows & reattachment. In this tutorial the backward facing step problem is used to demonstrate the use of Eulerian Wall Film (EWF) model for predicting the separation of liquid film. The EWF model can be used to predict the formation and flow of thin liquid films on wall surfaces. This model can be used with: • Discrete Phase Model – Particles are collected on the wall to form the film. • Eulerian Multiphase Model – Secondary phase mass is collected on the wall to form the film. In EWF model, the film is not resolved using mesh normal to the surface, instead this model uses a vir- tual film on the surface. In many cases you would be interested in modeling a thin film flow which can separate, strip and evaporate but does not affect the core flow-field. In general multiphase frame work, this thin film modeling is computationally expensive because a very fine mesh is required near the surface to resolve the film and the inter-phase flux needs to be calculated accurately. EWF model can only be used with 3D solver and EWF model assumes that film always flows parallel to the surface so normal component of film velocity is zero. The film is assumed to have a parabolic velocity profile & bilinear temperature profile across its depth. In this tutorial you will learn to: • Couple EWF model with Discrete Phase Model to create film. • Model detachment of film at edge. • Model film heat transfer. |
