Supersonic Shock Train Simulation
 

Hello, I'm trying to simulate a shock train formed in a rectangular duct under supersonic conditions by referring a research paper.
Boundary Conditions - Pressure Inlet - Total Pressure= 310,000 Pa, Static Pressure= 16,535 Pa Total Temp = 289K
Pressure Outlet - Static Pressure = 99,000 Pa.
Density based solver, Ive tried k-epsilon and k-w sst.

However, when I run the simulation, I'm unable to get a convergent solution and I am unable to replicate the results of the research paper.
If anyone has done a similar simulation, could you please guide me?
Thanks

Can you produce the residual curves?
