CEL problem
Dear all,
I use the eulerian-eulerian two phase model and treat both the water and air phase as continuous phase in my simulation,then I want to use the following drag correlation.Now I don't know how can I realize it.I want to use CEL but i can't find where to define the VS(superficial gas velocity).thanks a lot!

hi rainining.

define a new expression then make a right click and in the part of "variables" in the menu of "specific heat capacity at constant volume" you can find "superficial velocity" .
is it what you want?

i hope i could help you.

Thanks for your answer, I have found the superficial velocity(X,Y,Z) according to your answer,but I have no idea about which phase the superficial velocity stands for, GAS or LIQUID ,because I use the multiphase model.HOPE FOR YOUR ANSWER ,thanks.

you can find the definition and folmulation of this variable in

or by search in google
