To probe: Click on "Probe" icon. Then change the variable to "Velocity" and click on the screen where you wanna probe.

Vorticity Contours

Another interesting thing to analyze is the Vorticity distribution downstream of the turbine. This strongly affects how you would distribute more turbines in case you are designing an array of them.

But to do that we have to tell Fluent to export Vorticity Magnitude to CFD-Post. To do that, go back to Workbench, and double click "Solution".

Under "Run Calculation", click on "Data File Quantities". Select "Vorticity Magnitude" from the list and click Ok.

Run the simulation again so Fluent can retrieve the desired value. It will converge in 2 iterations. Close Fluent

Open CFD-Post and create a new contour. Name it "Vorticity Contours"

Tip speed ratio (TSR)

In practice, this is extracted directly from the Boundary Conditions, since we will essentially check that the velocity at the wall is zero. Therefore the purpose of this check is more to verify if we had correctly inputted the mathematical model into Fluent.
