Numerical Results
Depending on the mesh used, values for the torque on the blade can range from 0.02 to 0.04 N-m for the simulation as it was shown in the videos. Newer versions of ANSYS may use a different cell count, mesh quality, and solver algorithm which accounts for this discrepancy.
In CFD-Post, when calculating the torque, newer versions of ANSYS do not let you select "Air" as the fluid. The two options under the "Fluid" dropdown are "All Fluids" and "Mixed" - the recommended selection is "All Fluids", but both selections should give you the same final answer for the torque.
