FLOW AND HEAT-TRANSFER OVER A LONGITUDINAL CIRCULAR-CYLINDER MOVING IN PARALLEL OR REVERSELY TO A FREE-STREAM

Steady laminar boundary layer flow and heat transfer over a thin longi tudinal isothermal circular cylinder moving in a flowing stream has be en studied in this paper. The cases in which the cylinder is moving in the same (parallel) or in the opposite (reverse) direction to the fre e stream are considered. The transformed nonsimilar boundary layer equ ations are solved numerically using the Keller-box method for some val ues of the curvature parameter, the Prandtl number and relative veloci ty parameter. The results show that the velocity and temperature distr ibutions as well as the coefficients of skin friction and the local Nu sselt number are appreciably affected by the relative velocity paramet er.
