VOF and droplet impact
Good morning, my name is Simone and I will need to work on a simulation of an impacting droplet. CFX has developed a VOF algorithm but I do not know where to start to work with it.

Anyone is using it for free-surface fluids or multiphase flows with free boundaries (droplets moving in air) and could tell me where to start and what gridding tool i sbest?

thank yo uveyr much for the help,

Re: VOF and droplet impact
Have you read the section starting on page 133 in the manual?

Ask CFX support to send you a copy of their surface tension model verification report.

Re: VOF and droplet impact
hello, thank you very much for answering; I actually have way too many manuals in the folders of CFX; which manual exactly are you mentioning?

thanks again,
