What should be the boundary condition for this case ?
Hello, I am trying to simulate this paper and I am stuck at this. I have tried piecewise polynomial function for specific heat and Ideal gas for density for air and for inlet condition I have used mass flow inlet and specified mass flow rate and temperature and for outlet pressure outlet. Still I am getting around 80K error. What should be the boundary conditions ? I have also tried applying gauge pressure with mass flow rate but solution diverges ? I have checked mesh quality.
