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
