Default How to control pressure jump in a fan?
Posts: n/a

I'm doing a project in which I need to create the performance curve of a fan (pressure jump versus flow rate) and I'm having problems with the boundary conditions, I have tried pressure inlet and pressure outlet, 2 pressure outlets and finally mass flow inlet and outflow. With the last one Fluent doesn't make anything, and tells me that k diverges.

Can somebody tell me which one of the 3 boundary conditions is better for my purpose, and if it is the third one, does anyone know what the problem is?

Thank you

Tutorial 8, Using multiple rotating reference frames deals with a centrifugal blower, pressure-inlet and pressure outlet are used, k-epsilon turbulence model. Check your mesh and Good Luck
