The paper describes a novel implementation of the piecewise linear interface-capturing volume-of-fluid method (PLIC-VOF) in axisymmetric cylindrical coordinates. principal innovative feature involved this work is that both forward and inverse reconstruction problems are solved analytically, resulting an appreciable speed-up computing time comparison with iterative approach. All formulae introdu...

In this study, an efficient conversion algorithm of level set function ϕ from volume fraction α is developed. This method makes the calculation easier than conventional CLSVOF method, and precision surface tension can be improved by application ϕ. The two numerical tests are shown to demonstrate proposed scheme. As a result demonstration tests, it obtained that (a) gives better existing simple ...

When a hydrogen or oxygen bubble is created on the surface of an electrode, micro-convective vortex flow due to Marangoni effect generated at bottom in contact with electrode. In order study such phenomenon numerically, it necessary be able simulate tension variations along liquid-gas interface, integrate mass transfer across interface from dissolved species present electrolyte gas phase, and t...

This study investigates the potential of a newly released multi-phase solver to simulate atomisation in an air-blast type atomiser. The 'VOF-to-DPM' was used primary and secondar...
