FLOW OF A MICROPOLAR FLUID OVER A CURVED STRETCHING SURFACE

The paper is devoted to the numerical solution of the problem of flow of a micropolar fluid over a curved stretching surface. A similarity transformation is applied to reduce a system of partial differential equations to a system of ordinary differential equations. The numerical solution of these coupled equations is carried out by the shooting method using the Runge-Kutta algorithm. The physical quantities of interest, like the fluid velocity, microrotation velocity, and pressure, are obtained and discussed as functions of the nondimensional curvature radius. It is evident from the results that the pressure inside the boundary layer cannot be neglected for a curved stretching sheet, as distinct from a flat stretching sheet.
