Performing a simulation on a NACA 2412 Hydrofoil at a 4 aoa

I am performing an analysis on a NACA 2412 hydrofoil that is positioned at a 4 degree angle of attack. I want to test for cavitation formation. However, I am first doing it for velocity and pressure magnitudes. The test will run at a speed of 15 m/s. I had an issue when first trying this where there was a pressure problem near the trailing edge for being really sharp. I have made a fillet on the trailing edge to elimnate that sharp edge that caused the problem. I am wondering if the mesh I created for the new modified hydrofoil will work.




Hi @VorCavPro, thanks for posting on the forum and welcome to the SimScale Community :handshake:

Looking at your mesh near the trailing edge, now it’s visible that the boundary layers don’t seem to be breaking:

Which should suffice for the convergence of the simulation. Looking at the meshing log, your Non-orthogonality still seems a bit high:

Taking a look at this article might be helpful in solving meshing issues:

A final piece of advice is to define area averages to the inlet/outlet so that you can manually observe the convergence of the run there.

Is that helpful?

Cheers
