Unsteady flow over a stretching surface in a rotating fluid

Abstract

The unsteady laminar, incompressible boundary layer flow caused by the stretching of a flat surface in a rotating fluid has been studied when the surface is stretched in a particular manner. The partial differential equations governing the semi-similar case and the ordinary differential equations governing the self-similar case have been solved numerically using the finite-difference scheme in combination with the quasilinearization technique. The solution is found to depend on a parameter λ which signifies the relative importance of rotation rate to stretching rate. The effect of power-law variation of the surface temperature and surface heat flux on the heat transfer characteristics of the stretching surface has been analysed. The temperature parameter ( m) is found to play an important role in the heat transfer characteristics of the surface. The magnitude of m affects the direction of flow and quantity of heat transfer. For m = −1, there is no heat transfer occurring between the stretching surface and the ambient fluid in the steady state for prescribed wall temperature.
