Secondary fluid mass flow rate

Hi,

 

I am very new to Autodesk Simulation CFD and really need some assistance. I attempting to simulate a convergent divergent nozzle with an area ratio of 2 with  a secondary injection opposing the primary flow to determine outlet flow rates and vectoring coefficients the 2D simulations (Geometry attached) I have already attempted the mass flow rate boundary condition set at the secondary injection port does take effect during the simulation. Would it be possible to get some advise on how to fix this problem?

 

 

Thanks in advance!

Hi,

 

Are you running a 2D axisymmetric analysis here?

Do you have the basic nozzle set up and working? It might be worth getting that running well first and then adding the extra inlet.

 

Could you share a more detailed description of your setup? With Materials, Boundary Counditions, Mesh and  Solver Settings included?

 

Thanks,

Jon
