jetflow
hello
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.. |
Compare with experimental to choose the right model

v2f is the best model for jet flow .check this http://adf.ly/1dJ45q to see how to activate it
