Actuator disk Ueq approach!

tareqkh · May 31, 2017, 02:34

Hi All,

I am working on the implementations of the actuator disk and blade element theory using Ueq approach. My aim is to implement it so that I can apply wedge boundary condition. The problem is that the body forces from the blade element theory have to be transformed to body forces in x, y and z becuase OpenFoam uses Cartesian coordinates. What force should be excluded to make it match wedge boundary condition. I have asked this question so many times and no luck on finding an answer. I can provide more details if needed. Also, I can clarify my writing if it is not clear. Please I am seeking help to resolve this issue forever.

Thanks in advance for your kind help,

Regards,

Quick answer: The closest I know about this is that "Virtual Blade Model" was implemented in Caelus-CML (it's a fork of OpenFOAM) sometime ago... in version 7.04.
Try to look into its code and tutorial cases for ideas: http://www.caelus-cml.com
