Question
A fixed cylinder of diameter D and length L , immersed in a
stream flowing normal to its axis at velocity U , will experience
zero average lift. However, if the cylinder is rotating
at angular velocity V , a lift force F will arise. The fl uid
density ρ is important, but viscosity is secondary and can
be neglected. Formulate this lift behavior as a dimensionless
function.
