I am working on the CFD simulation of supersonic rocket nozzle flow separation with turbulence modelling (2D axisymmetric). I have tried a Menters SST, SA turbulence model in CFD++ commertial package. The results I am getting is not matching with the literature (DOI: 10.2514/6.2015-4220
) data. I am following same specification as given in literature but results are not matching.
I am attaching my result with this post.

Is anybody know, what can be the possible error ?

please suggest

I do not see anything wrong with it. CFD is like this. In fact, I would be very surprised if your solution matches the other perfectly. Nevertheless, I can suggest you comparing the discretization technique used for both computations as well as the method used.
I guess you follow the procedure to obtain a grid independent solution. Try to check the numerical approach used for your case and the reference.

Thanks juliom , I will follow through your suggestions
