Calculate RPM

ahahha · December 11, 2010, 22:06

hi all,

i would know that is that possible to determine the rpm of rotor by giving air flow rate and velocity?

furthermore, what application i should used?
cfx, fluent, or etc?

thanks for the help

this would be of my interest, too!
I only know that one can determine the angular velocity in rpm as a fixed value (or altering with the help of an UDF) for MRF or sliding mesh (fluent)
but is it possible to calculate the rotational speed due to the input of mass flow?

regards
