how to calculate axial and radial velocities from a turbulent kinetic energy value

    • aidan4321

      I have completed a steady state simulation using a k-epsilon model

      I then extracted the turbulent kinetic energy at the points required in my model

      I am unsure how to use this data to obtain axial and radial rms velocities?


      All help is much appreciated

      Thanks in advance!

      RMS values are calculated in Fluent, and are activated from the Iterate panel. This must be done once you have a reasonably stable solution, and then further iterations are calculated to get the data. Otherwise velocity data is available from the solver directly.

      Firstly, thank you for your response.

      Secondly, I have looked though all the menus within fluent and am still unable to find an option for RMS velocity values. 

      I have been instructed to extract the turbulent kinetic energy and then use Urms=sqrt(2Ke/3) to obtain values. 

      However, This approach does not give rise to both the axial RMS and radial RMS velocities required.


      Again any help is greatly appreciated!
