Influence of surface tension implementation in Volume of Fluid and coupled Volume of Fluid with Level Set methods for bubble growth and detachment

A simple coupled Volume of Fluid (VOF) with Level Set (LS) method (S-CLSVOF) for improved surface tension implementation is proposed and tested by comparison against a standard VOF solver and experimental observations. A CFD Open source solver library (OpenFOAM®) is used for the VOF method, where the volume fraction is advected algebraically using a compressive scheme. This method has been found not to be suitable for problems with high surface …
