SOWFA-6, Actuator disk application: bladeForceProjectionType and "lineToDiskGaussian3D";

[TrailblazerH]

Hi,

I am applying the body force projection method "lineToDiskGaussian3D" in SOWFA 6 to run an actuator disk simulation. I have seen that no matter AD or AL method, there is always a little part at the hub position. I mean the body force goes to zero as closing to blade root. I want to know if it is possible to exclude this part in the center of the hub by simply adjusting input parameters to SOWFA and make it more like a pure rotor disk. Because right now it can be observed that there is a little circle in the center of the disk.

Before I thought this is due to the nacelle, I exclude nacelle. It is still there. I think this is related to the body force projection and technically it should be possible by adjusting the Gaussian width to realize it as I expected, right?

Thank you

Hi,
have you tried to set "HubRad" to 0? And in the same file add one line in "BladeData" where radius is 0 and use a cylinder as airfoil.
