Unsteady Flow and Heat Transfer in a Viscous Incompressible Fluid due to the Oscillations of a Porous Cylinder with Suction

Abstract

Navier-Stokes equations which described the unsteady flow of viscous incompressible fluid a around a porous infinite circular cylinder oscillating harmonically with constant suction are integrated using Laplace transform. Curves have been drawn of the steady state part of the velocity both for suction and without suction case and it is found that for each value of suction parameter a situation which does not exist in the case of rotating cylinder. The energy equation has also been solved and the solutions are given for large and small values of time.
