Turbulent kinetic Energy
Hello,
I have a 3x3x3 mesh grid (chosen for simplicity) that I am using to analyze turbulent velocities. The turbulence is isotropic.
I have uvelocity measurements (fluctuations) made on the grid that were taken at some time, t. I also have v and w velocities that are the same size.
I would like to find the turbulent kinetic energy by using the equation (u )
What I am stuck on is understanding how to apply this equation to my data.
In example, if I wanted to plot TKE vs. t, I should only get a single point, right?
How do I boil down this data to get the single point?
Any help is appreciated.
