Moment Coefficient for a 3D Rotating Cylinder

[richvaso]

Hi,

I'm looking for the Moment Coefficient (Cm) for a 3D Rotating Cylinder, this means, I there is a free stream of fluid and there is inmerse a cylinder rotating about its own axis , and also rotating about an axis parallel to the free stream.

I found in the book of Peter Childs, called Rotating Flow, the Cm for a rotating cylinder with flow parallel to its axis.

Well, the first thing that I need and maybe some one helps, is the reference of where can I find the Cm for the rotating cylinder with flow perpendicular to its axis.

I hope this exist, but sincerely I did not found it.

Then, the final goal is figure out how to calculate the Cm in the 3D situation.

Thanks!

</code>Unfortunately, there is no clear answer to your question as the exact value of Cm for a rotating cylinder in a 3D situation depends on a number of factors, such as the Reynolds number, the airfoil's geometry, and the angle of attack. The best way to find out this information is to consult research papers and scholarly articles related to this topic. You can also consult textbooks or other resources that discuss this topic in depth.
