Motion of a Viscous Fluid Contained in a Cylinder of Infinite Length Subjected to Longitudinal and Torsional Oscillations of Independent Amplitudes
Wendell Phillips, Karim Rahaman

The motion of a viscous fluid contained in a cylinder of infinite length subjected to longitudinal and torsional oscillations is investigated. The governing equations are obtained and these are used to derive expressions for the shear stresses and drag forces on the interior wall of the cylinder, as well as the drag coefficient and work done by the drag forces. Graphs are plotted to illustrate the behaviour of the velocity components and other expressions derived in this investigation.
