Separete position in nozzle
 

Hello,

I use Fluent to calculate the Vulcain nozzle problem with NPR = 20,40,80, 110. My problem is coupled , 2d, implicit, steady problem. Use the Standard K-Epsilon as the viscous model.

My question is : When i increase the inlet pressure from NPR=80 to 110 the separete position doesn't change. Now i m trying with the K-Omega SST vicous model with a coarse grid but i think that it will has the same result???

Anybody have ideas ? It s urgent

Thanks very much.

hi steve im also working on compressible fluid flow. i want to calculate temperature distribution in the jet deflector of rocket engine. i want to model first in 2-d, can u give me any idea regarding this? which nethod i have to follow for this calculation? i have all the nozzle exit properties, i,e these may be inlet to the deflector system waiting for your reply bye satya
