摘要为了方便、准确地模拟电场作用下气泡的动力学行为,首次提出了基于FLUENT的VOF+LS+SPP方法。与基于FLUENT的VOF和VOF+LS方法相比,VOF+LS+SPP方法具有很高的精度,最大偏差仅为7%。其模拟结果上级优于文献中的波前跟踪法、LS法和相场法的模拟结果,与VOSET法的模拟结果基本一致。最后,利用所提出的方法研究了不同介电常数比下气泡变形的规律和机理。
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.
