what is the best turbulence model in jetflow simulation?
the air(ideal gas) is compressible and i used the velocity inlet(velocity=150m/s) and pressure outlet as the paper that im trying to validate mentioned...the goal is acoustic analysis..
this paper used sst kw model ....but when i use it the acoustic pressure is different from what is in the paper...
i used all of the models and i got different answers
in k e standard=there is no swirl in the velocity contours and acoustic pressure is between -40 to 40
in k e Rng and realiziable=there is a swirl in the velocity contour and acoustic pressure is between -600 to 600
in k w sst=is like Rng and acoustic pressure is between -800 to 800
which one is right?
the acoustic pressure in the paper is oscillating between -80 to 80
i hope some one could help me..
