Local Similarity Solutions for Laminar Boundary Layer Flow along a Moving Cylinder in a Parallel Stream

The present paper deals with a numerical method to analyze the axisymmetric boundary layer flow of a viscous and incompressible fluid along a static or moving cylinder, using local similarity approximation. Both parallel and reverse moving boundary to the free stream are considered. Local similarity solutions are obtained to show the effects of the velocity ratio parameter and the curvature parameter on the surface shear stress. The numerical results are comparable very well with the existing results available in the literature for some particular cases of the present problem. Moreover, the results indicate that dual solutions exist when the cylinder and the free stream move in opposite directions.
