Hi,
I have done CFD simulation of a wind turbine and now I need to plot the T.I values behind the plane. I can plot T.K.E, but is there any way other than using the expression.
Define a new expression sqrt(2/3*Turbulence Kinetic Energy) /Velocity. Then define a user defined variable by using this expression. This new variable can be plotted.
Hi
often TKE is normalized with mean inlet velocity v_in^2. If you calculate oscilatory flow, with a peak (for instance the mean flow is developing according a sinusoidal curve), then do normalize with the peak inlet velocity v_in^2.
Two options, one is to define a new expression in CFD-Post as explained above by Jörg Wolters.
Second, if you are using fluent for simulations, you can always define turbulent intensity as a custom field function (or use the built-in one) and save it as a user-defined memory (UDM). Once you export the fluent .dat file into CFD-Post, the UDM is available.
