Supersonic static pressure
Hi, I'm quite new with Star CCM+.
I am trying to simulate a flow inside an axial turbine.
I am using steady state couple flow.
The boundary conditions are from a real model gas turbine.
I set the inlet condition to be a stagnation inlet.
The problem is that is asks for a supersonic static pressure? Does anyone know how can I can get this value.
I have been doing the same simulation using Ansys CFX. But the mach number at the inlet shows no sign of sonic flow. so does it mean that the I should leave it as 0? or should i use the mach number relation to get the static pressure?
If I use the mach number relation, the static pressure will almost equal the total pressure since the mach number at the inlet is 0.12.
