turbulence intensity for temperature

      Hi,


      I am doing turbulence simulation in Ansys Fluent by using the k-kl-omega model. I need to compute the turbulence intensity for the temperature, but it seems only possible to get it for the velocity. Is there a way also for the temperature?


      Thanks in advance.

      Never heard about that. I guess you want to check the RMSE of temperature field?

      Hi,


      yes, for the velocities is the RMS of the fluctuations divided by the mean velocity of the fluid. For the temperature is the same, but divided by the difference between Twall and Tmean.


      Best regards.

      You can enable data sampling and use values of RMSE to build-up whatever you want.

      Thanks. Do you know if it is possible to find the RMSE values in results or you can only work with them in solutions?

      They are accessible as solution variables.
