Supersonic Nozzle Flow Analysis

Hello,

I am designing a supersonic nozzle and I am using the solidworks flow simulation package to analyze the flow. I have a couple of questions.

Firstly,

How do I find the exit pressure of the nozzle over the exit plane? I tried to do an XY plot using the exit edge but I am pretty sure it just giving the exit pressure at the boundary.

 

Secondly,

I have designed a nozzle using another software and it not performing optimally. It is over-expanded. I am trying to find the correct inlet pressure to provide the correct exit pressure (Pe = Pa). To do this, I am simply using a bracketing method, just trial and error until I find the correct pressure ratio. Does solidworks have a way to do this for me?

 

Thanks,

James Emerson Parkus
