Effect of a Plane Wall on the Impulsive Motion of a Sphere in a Viscous Fluid

Abstract

The impulsive motion of a sphere along a plane wall in a viscous fluid is treated on the basis of the Stokes approximation. A solution to the equations for unsteady motion is obtained by applying the Laplace transformation with respect to time to the basic equations. Results obtained to a first approximation for the drag and the torque acting on the sphere show that: \renewcommand\labelenumi\arabicenumi.
