nozzle master is on a distinguished road
In order to analyze the flow inside the nozzle, a 2D Axisymmetric nozzle is simulated.

Other nozzle model is fine. They have same mass flow rate between throat and exit in nozzle.

But only one thing have not same mass flow rate.

Mass flow rate of throat is about twice more than the mass flow rate of exit.

What happen this situation?
What is wrong ... ? :혼란스러운::혼란스러운:

말도 안돼,


There's no way that can be a converged result. Have you plotted contours of pressure/temperature/velocity throughout the domain? It's probably all bonkers.
