hi
i want to model a channel with sediment,water and air (3phases). how can i do it?
it is immediate for me, please help me.

A number of ways. The easiest way is probably to create 2 continuous fluids, Air at 25C, Water, and a dispersed particulate solid phase to represent the sediment. Turn on buoyancy, initialize the domain with the free surface in place, and other than including the dispersed solid, follow the tutorials on free surface flow.

PS, I hate questions like this. "I need to build a car. How do I do it?"

s_baghalian · October 13, 2010, 18:00

what??? i don't know how do it so how can i question it???
i read free surface tutorial but i have a model with 3 phases.i want a example or tutorial about it that i read it. is it possible?

what are the expressions in a 3phases model with sediment,water and air?

Work them out.

please introduce a book or tutorial or guide for modeling it please.
i need to help you. i haven't any reference or guide about it.

The CFX tutorials are the best place to start.
