I'm need to determine the rate of spin decay for spherical objects as they're passing through air.
Basically, I'm trying to model the Magnus Effect and the output I'm getting doesn't reflect reality. I hope that I can obtain better results if I'm ab;e tp determine the rate at which a sphere's angular velocity decreases.
Does anybody know the equations necessary to calculate spin decay?
For the situation I know the mass / size of the object and the air density. My guess is that there is some sort of friction coeffecient that needs to be estimated or determined. Beyond that, I'm at a loss as to how to calculate spin decay. Any ideas or advice would be appreciated.
Thanks,
Nathan
