A Study of Mixed Convection Flow over Stretching Cylinder in Presence of Slip Flow and Thermal Jump Boundary Conditions

Abstract

The present work focuses on the study of flow and heat transfer in the axisymmetric flow of a viscous incompressible fluid over a permeable vertical stretching cylinder. The flow model is studied for the second order slip flow and first order thermal jump boundary condition. The governing equations of continuity, momentum and energy are transformed into system of non-linear ordinary differential equations and solved numerically. The velocity and temperature distributions are discussed and shown through graphs. The effects of various physical parameters are examined and discussed in detail. The expressions of skin-friction coefficient and Nusselt number at the cylinder are discussed and their variations are presented through tables. It is found that the increase in first and second order slip parameters increases the fluid velocity while temperature distribution is not considerably affected. Further, the increase in thermal jump parameter tends to increase fluid velocity and temperature.
