Hello,
I try to simulate a propeller NACA 6623-A published in NACA 650, 1939. But my results are different from the data. The efficiency is only 0.42 at advance radio=0.65 as well as that from the data is 0.8. The following is how I calculated the efficiency: force_z()@BladeSurface torque_z()@BladeSurface*25.24*2*3.1415926 ForceZ*massFlowAve(Velocity in Stn Frame w)@Inlet/Power (the rotation speed of the propeller is 1514 rpm) If CFX-pre(.def) setting is need, please tell me your e-mail. Thank you very much. Liu |
