Synthetic inlet turbulence

Hello Friends,
I am currently investigating fluid mixing in T junction pipe flows using ANSYS CFX. I wanted to implement artificial/synthetic turbulence at the inlet of main pipe (hot fluid pipe). Therefore I thought that I could create a separate geometry of 10D length only for the hot pipe and implement synthetic turbulence and give the turbulent output of the separate upstream geometry as the inlet of T junction main pipe. I am using CFX Version 14.0. I read CFX manual and could not understand how to implement it. In the ANSYS manual titled Scale resolving turbulence, it was mentioned that CFX has a Harmonic Turbulence Generator for creating synthetic turbulence. But there is very little explanation as to how to do it. Is this option explicitly mentioned in CFX or is it an in built feature in one of the models like SST, SAS or DES? Thank you in advance for your guidance and help. Regards, Karthick Selvam. |

I have never used it so cannot help you. I would ask CFX support for help on this.
