May 31, 2011, 16:27	Stratified flow modelling	#1
Reza_computational New Member Join Date: May 2010 Location: Tehran, Iran Posts: 20 Rep Power: 15	Hello dear users I want to model water and air flow through a pipe in which the flow pattern is stratified flow. I need to find a gross amount of pressure drop of fluids. I used eulerian-eulerian inhomogeneous model for the solution. The problem is that CFX needs a drag coefficient to start simulation. CFX default value is 0.44 for drag coefficient. I will appriciate your help on this drag coe. and exactly where i can find a trustable reference for this value... Thanks in advance...
