VOF (Volume of Fluid) CFD Training Package (Part-II)
The Volume of Fluid (VOF) CFD Training Package (Part-I)
This CFD training package contains eight different products, applying the VOF multiphase model by ANSYS Fluent software. This CFD training package will help get familiar with professional industrial and academic CFD projects in the VOF multiphase area.
This multiphase method method has the advantages of easy realization, low computational complexity, and high accuracy. It also detects the liquids fraction in the grid, not the movement of fluid particles. To obtain the interface, we trace the αk volume fraction of each k phase in a computational cell across the domain, we sould use VOF method. If αk = 1, this indicates that the cell is filled with k phase, αk = 0, it indicates that the cell does not have k phase. For 0 <αk <1, the cell contains the interface between the two phases (VOF).
A VOF based model for solving two-phase flow problems in which the longitudinal scale of the interface is larger than the grid dimension, such as the flow in the upper part of the spillway, is acceptable but fails in flows where the longitudinal scale of the interface is smaller than the grid dimension.
There are lots of CFD simulation projects that should apply the Volume of Fluid multiphase flow. We use the VOF multiphase method to simulate Distillation Column Tray, Mixer Tank , Surface Evaporation of a falling water droplet, open channel, ejector, oscillatory wave, injector, etc.
All files, including Geometry, Mesh, Case & Data, are available in Simulation File. By the way, Training File presents how to solve the problem and extract all desired results.
