自軸まわりに回転する円柱に作用する力（定常回転する場合）

Abstract

The Magnus force on a rotating body traveling through a fluid is partly responsible for the inaccuracy and dispersion of ballistic missiles and rifle shells. A great deal of efforts has been done to predict the detail behaviors of the force under various conditions. Most of them, however, are experimental studies about time-independent ambient flows. The behavior of the force acting on a time-dependent rotating cylinder has not yet studied sufficiently. As a first step to the time-dependent flow problem, this paper describes details of the forces on a constant-speed rotating cylinder in relation to the velocity ratio; peripheral velocity of cylinder/free stream velocity.
