Hi,

I have to simulate the compressible flow of oxygen in considering the equation of state of Redlich-kwong,although floworks doesn't allow the High mach number option for real gas.

Someone knows if a macro can fixed this problem thanks.

Thank you Jared for your answer.

And so ,do you know a method to estimate the temperature and the pressure with a real gas equation of state from the values obtained thanks to the ideal gas simulations.Thank you again for your help, although the most important for me is to determine the temperature cause I have to compare it with some measured temperatures.

And so I think maybe if I could use the pressure and the density from the ideal gas simulation then use them to compute the temperature with the redlich-kwong state's equation I'll can obtain a more accurate temperature than from the ideal gas simulation clearly overestimated.The fact is the navier-stokes equations are coupled for the resolution and I don't know if floworks determine the pressure thanks to the conservation of momentum equation or thanks to the equation of state.

use an ideal gas

it is a limitation of the software, no macro can change that behavior
