varying contact area of splashing oil with surface

rakeshpe · August 29, 2019, 06:55

Hi guys,

I was attending a transient two phase flow problem in which an oil is splashing over the surfaces around it. initial contact area is defined.

I wanted to find the contact area variation of oil with time.

Can anyone help me.

What are the other substances, which are not oil? Please draw the initial conditions and what you expect to occur.

The CEL expression areaInt(oil.Volume Fraction)@surface name will give you the wetted area of a phase called "oil" on a surface named "surface".

i have two phases, one is oil and other is a gas. at initial contact area is defined. but on the transient run, oil will splash around and the varying contact area is what i am looking for.

hope you got an idea..
