Using 6dof for 3D turbine rotation
Hi, I am working on a problem where I have a turbine driven by the flow. My intention is to use 6dof and rotate the turbine along with the enclosed zone (similar to what we do in sliding mesh where layering, smoothing and remeshing will not take place).
The approach I am doing is
1. hooking 6dof to Turbine (which is defined as wall in BC) with 6dof-on, passive-off
2. Hooking 6dof to fluid Zone enclosing the turbine (which has all exterior surfaces defined as interface). The only wall inside the zone is turbine. here 6dof-on, passive-on
Will this kind of a strategy calculate fluid forces and moments on the turbine and rotate the turbine along with the zone enclosing it?
My axis of rotation is Y and I am restricting the all translation and x,z rotation using
prop[SDOF_LOAD_LOCAL] = TRUE;
prop[SDOF_ZERO_TRANS_X] = TRUE;
prop[SDOF_ZERO_TRANS_Y] = TRUE;
prop[SDOF_ZERO_TRANS_Z] = TRUE;
prop[SDOF_ZERO_ROT_X] = TRUE;
prop[SDOF_ZERO_ROT_Z] = TRUE;
Please discuss if you have some thoughts..

I am working on something very similar. I have a turbine in a pipe with a rotating zone around the rotor.
Have you made progress with your simulation? Did it work?
