Nonsimilar Solutions of Unsteady Mixed Convection Along a Moving Cylinder

Abstract

This paper describes the nonsimilar solutions of unsteady mixed convection along a moving cylinder. The problem is formulated in a more general fashion by using the parameter \(\lambda \). When \(\lambda =0\), we have the case of stationary cylinder in a moving stream, whereas when \(\lambda =1\) we have the case of moving cylinder with no external motion imposed on the free stream. For the intermediate values of \(\lambda \) we have the case of simultaneous motion of the cylinder and the free stream. The governing unsteady boundary layer equations (nonlinear coupled PDEs) are solved by the quasilinearization technique. Fluid flow and heat transfer characteristics for a variety of accelerating and decelerating situations are presented graphically and discussed.
