Best VOF model for high pressure convective boiling simulation

Jefferson2010 · August 31, 2018, 11:33

Dear all,
I want to use VOF to simulate high pressure convective boiling. In high pressure boiling around 45 bars, the size of the bubble is very small. The radius is around 4*10^(-5)m. Due to boiling, there is volume expansion near the interface. I want to keep the interface sharp and reduce smearing, especially near the wall boundary. In Fluent 16.2.3 manual, it mentions five VOF methods:the geometric reconstruction scheme, the donor-acceptor scheme, CICSAM, the compressive scheme and BGM. Here is the link: https://www.sharcnet.ca/Software/Ans...ec_vof_eq.html
Could anybody tell me which scheme is the best for my case? If other schemes compared with those five are better, please also tell me. Thanks in advance!
Best regards,
Wentao Guo

Generally reconstruction method is used. But don't what should use for your problem.
