Week 10 - MRF project

Objective: The objective of this project is to provide guidelines and recommendations for the Moving Reference Frame (MRF) fan modeling technique in ANSYS Icepak for the given CAD model.

Problem Description:

An Icepak 3D fan object behaves differently from real fan behavior. The reason for this is flow features like swirl and centrifugal spread due to spinning fan rotor as well as the rotor blade geometry. In an Icepak fan-based setup, this swirl is estimated and calculated off a 2D annular flow face rather than off the physical surfaces of the blade.

The MRF approach provides accurate geometry of the fan and therefore results in better modeling of the flow features. In Icepak MRF simulations, the actual blade geometry is modeled as a CAD block object and a fluid cylinder rotates into contact with the surfaces to create a spinning flow.
