Hi guys,
I'm meshing an axial fan. My question is: how fine should be that mesh around blade surface if I wanna discretize part of the boundary layer, but without a specific boundary layer analysis.
I just have to know the velocity field forward and backword the fan into a pipe to get the delivery vs static pressure.

What I have is: diameter of the fan, number of blades, all the geometrical dimension, fan RPM.

Thanks a lot

Hi,

There is a workshop written by ansys about a simulation of axial fan. If i am not wrong, this is a workshop from version 14.0 of Ansys.

diamondx will become famous soon enough
ansys customer portal website, just google it. It doesn't take too much time to create account there. they offer a bunch of material training and quick tutorials and documentation about their products.
