I have case of a rotating fan at Low- speed ie about 300-400 rpm. I have successfully carried out RAS simulations using cyclicAMI approach where, the motion of the fan is modeled as rigid body rotation of a cylindrical AMI mesh section, which has same speed as our fan. I have tried various levels of mesh refinement and differing y+ and so forth.
I would like to know if there are any other methods of modelling this problem, as I am not able to predict some important parameters accurately. For the attached mesh I used solidBodyMotionFvMesh for rotating inner domain/cyclicAMI. I am looking into dynamicFvRefineFvMesh and dynamicMotionSolverFvMesh for rotating the fan.
please let me know which other approach is suitable and how to set-up the mesh for such case (pointers to examples would be great)
PS : Motion of the fan is strictly rotation about a fixed axis.
I would like to know any other way (except below accepted answer) of conducting this simulation.[cry for more answers]
