G'day,
I'm looking for some help with NASA'a RVCQ3D code regarding the omega input. The users manual that they provide for RVCQ3D states that the rotational parameter is defined as: Omega = (Wheel speed in rad/s)/c0. However, when using this equation, the output from the code gives the incorrect inlet conditions that my blade is design for. I have to increase the calculated value from 0.663 to approximately 0.775 in order to obtain the correct inlet conditions i'm looking for.
So i guess my overall question is: is the given equation in the manual correct, or should it be calculated another way? I've searched everywhere to find others work in order to back-calculate their omega values but haven't gotten anywhere. Any help would be fantastic!
