Calculate Control Valve Two Phase Flow
Calculate Control Valve Two Phase Flow
(OP)
I have a Cv for a control valve, and the material flowing consists of 15% ammonia in the liquid phase and some inert gases. I am not concerned with flashing of the ammonia, since the pressure is 300 psia and ambient temperature. I need to calculate the flow rate at a given pressure differential across the control valve.
Does anyone know of a way to calculate the flow rate of this two phase flow through the control valve?
If not, what about some good engineering estimations?
Thanks in advance,
Tony

The ISA Handbook of Control valves gives a procedure for predicting 2 phase flow thru valves .
