3D two phase flows numerical simulations by SL-VOF method

摘要

This paper describes the development of a semi-Lagrangian computational method for simulating complex 3D two phase flows. The Navier-Stokes equations are solved separately in both fluids using a robust pseudo-compressibility method able to deal with high density ratio. The interface tracking is achieved by the segment Lagrangian volume of fluid (SL-VOF) method. The 2D SL-VOF method using the concepts of VOF, piecewise linear interface calculation (PLIC) and Lagrangian advection of the interface is herein extended to 3D flows. Three different test cases of SL-VOF 3D are presented for validation and comparison either with 2D flows or with other numerical methods. A good agreement is observed in each case.
