Viscous damping acting on rotating disk

[bisherbas]

I am looking for a way to calculate the torque, hence the viscous damping coefficient per T = c*w, acting on a rotating metal disk in an oil sump. How can I go about it? Thanks!

PS. I am not a ME so please forgive my ignorance.

You may be able to find something in the fluid mechanics literature about the torque on a finite disk rotating in an infinite ocean of viscous fluid. I don't think it is something that you are going to find in everyday textbooks, and probably not on line. I assume you are not interested in setting up the problem and solving it yourself or using CFD software.

Thank you for the reply. Well I would be interested in that but I don't have the necessary skills to do so. I was hoping to find an answer online because I thought it would be a common fluid dynamics problem in the ME world. I could search the literature but I would need help with choosing the right keywords.

Try viscous drag on rotating disc.
