Volume of Fluid Modeling

October 20, 2023 8:00 AM – 10:00 AM CDT

Volume of fluid (VOF) methods are some of the most popular numerical techniques for locating and tracking moving and deforming interfaces between fluids in multi-phase flow simulations. In this workshop we will discuss the numerical details of the various VOF options in CONVERGE and go through some example cases and validation calculations. One of the VOF methods in CONVERGE is based on the species mass fraction equation and is appropriate for miscible or compressible multiphase flow calculations. CONVERGE offers an option for VOF-spray one-way coupling. In this option, CONVERGE collects detailed fluid flow information near the nozzle exit during a VOF simulation and then uses this information to inject parcels for Lagrangian spray calculations. Another VOF method, which solves for the void fraction directly, is available in CONVERGE as two separate schemes: Piecewise Linear Interface Calculation (PLIC) and High Resolution Interface Capturing (HRIC). These schemes have been tested on a range of problems including a rising bubble, a breaking dam, and an impinging jet.. Each test case illustrates the ability of the VFS method to capture the interfaces sharply.
*This session includes hands-on CONVERGE Studio practice.
