Hi,

This is my first post on the PhysicsFormus

I am trying to design an inlet and outlet for an axial fan and calculate velocity and pressure profiles in the duct. See the sketch attached. The ultimate goal is to carry out a CFD study but I was wondering if there is an analytical solution for a simplified case, so I can have some estimation. I did some research and was trying to apply "actuator disk theory" (linked), but I do not find the results believable (see spreadsheet attached, I simplified the problem to have a uniform section area).

Let me know if you have any suggestions on how to tackle this problem!

EDIT: Calculations and sketch attached, apologies for "Google-Driving" them first

Kind regards

Olek
