"The lift of a cylinder executing rotary motions in a uniform flow,"
*J. Fluid Mech.* **255**, 1-10.

*Abstract*

The mean lift coefficient of a circular cylinder executing
rotary motions in a uniform flow is investigated. These motions
include steady rotation, and rotary oscillations with a net
rotation rate. Results for the steadily rotating cylinder show
that for a given rotation rate, larger cylinder aspect ratios
yield higher lift coefficients. It was also found that the
addition of forced rotary oscillations to the steady rotation of
the cylinder increases the lift coefficient in the cases where
the wake would normally be separated in the steadily rotating
case, but decreases it otherwise. In addition, a method for
estimating the mean lift of a rotating cylinder is presented.
Estimates based on this method compare favourably with similar
data published for steadily rotating cylinders.
