Hi everyone!

I'm having some troubles! Let me explain...

I'm studying a wing, varying the incidence angle of the air flux: no problems with mesh or simulations, I am already in post-processing; I have been told to plot (in 3 plane sections I created), considering the varying angle:
1-velocity vectors;
2-relative pressure;
3-turbulent kinetic energy;
now, no problems with velocity and pressure.
I don't understand the plots of the turbulent kinetic energy: what is the meaning of all of these? How does it change when I reach the stall angle for the wing, and start to visualize the first vortex in the wake?
I can't find anything on my books...

Thank you!

As you can see by the definition of the TKE, it gives you information about the interaction of the turbulent fluctuations, or the kinetic energy per unit mass associated with eddies
