Discharge coefficient in function of pressure ratio
I calculated compressible high speed flow in steady state.
I determined the discharge coefficient from the results in case of some pressure ratio (pi = 0.6 - 0.125). Based on my calculations, the discharge coefficient is constant in this range. (alha = 0,85) The discharge coefficient was investigated at the full geometry.
What do you think about this? Can it be correct? Is there pressure ratio range where the discharge coeff. changes in the function of pressure ratio?
Discharge coefficients can be either constant over pressure ratio or variable. It depends on the details of the set up.
