Dear CFD Online members,

Currently I'm try to simulate a variable throat hydrogen re-circulation ejector.
I'm trying to simulate it with a sonic primary throat, hence a massflow and a pressure boundary condition on the primary inlet, a mass flow condition on the secondary inlet and a pressure condition on the outlet.

However, my simulation seem to diverge pretty quickly. Can someone help me with a solving strategy, I'm not really familiar yet with convergence enhancing.

In the following picture you can find the geometry, I meshed it in ansys mesher (triangular). The red represents the flow domain (it is an axissymmetric problem).



I hope anyone can help me out!

Kind Regards,

WernerJ
