RMS velocity in Cylindrical coordinates ?

September 12, 2006, 23:27

In FLUENT, we can get RMS(root-mean-square) velocities in Cartesian coordinates (x,y,z), also get z axial RMS velocity component in Cylindrical coordinates (r,θ,z). How to get the other two RMS velocity components ur_rms and uθ_rms in Cylindrical coordinates ?

thanks a lot.

Please how to solve the 3D problem in Fluent by using cylindrical coordinates? Regards, Celestin

I can only get solve velocities in Cartesian coordinates (x,y,z), I just want to get RMS velocity component in Cylindrical coordinates (r,θ,z).
