Should I use the transitional turbulence?

hopehope · November 14, 2012, 10:11

Hi. My job is to use CFX and model a 0.9*0.1*14m wind tunnel, inlet V=9.7m/s, outlet pressure=0. TO see the outlet profile. When I use SST, should I use the transitional turbulence? And which one should I use.
Also could anyone help me about that, or give me some basic information about transitional turbulence? I didn't find enough information in the help files.
Thank you!

Only use the transitional turbulence model if you think you have a turbulence transition and it plays a significant part in your flow. If not forget about it.

There are some papers on the turbulence transition model in the CFX customer portal and/or available from CFX support.
