Default Please help with momentum sources and actuatordisk
Posts: n/a
Hi all, I'm working with the actuator disk model in Fluent. I want to make a UDF file which assigns at each cell a source term which varies with the radius and the azimuthal angle of the rotor. The source term would be equal to the momentum coming from another programe that uses the blade element momentum theory. The values are stored in a file containing r, psi, force. They can be transformed to have x, y, force. How can I assign the right value of the mometnum source at the right cell?

How do you model actuator disk?

O made a zero thickness circular surface in gambit, but I don't know which boundary condition to give.
