Development of a VOF+LS+SPP method based on FLUENT for simulating bubble behaviors in the electric field

Abstract

To simulate bubble dynamic behaviors under an electric field conveniently and accurately, a volume-of-fluid, level set, and smoothed physical parameter (VOF+LS+SPP) method based on FLUENT is first proposed. Compared with the VOF and VOF+LS methods based on FLUENT, the VOF+LS+SPP method has very high precision and the maximum deviation is only 7%. In addition, its simulation results are superior to those results obtained by the front tracking, LS and phase field methods in the literature and almost the same with the data acquired by the VOSET method. Finally, the proposed method is used to investigate the law and mechanism of bubble deformation with different permittivity ratios.
