Conditions of Fluid Separation in Translational-Rotational Acceleration of Floating Elliptical Cylinder
A nonlinear transient problem on the joint motion of an ideal fluid and fully submerged elliptical cylinder at small times is considered. It is assumed that the cylinder moves from a quiescent state in a horizontal translational direction at a constant acceleration, and rotates around its own axis with a constant angular acceleration. The peculiarity of this problem is that the high acceleration of the cylinder having a low pressure area near the body and form a cavity. The author defines the exact conditions of the separation of fluid particles from the surface of the moving body.
