Flow and Heat Transfer of Power Law Fluid over Horizontal Stretching Cylinder with Partial Slip Condition and Thermal Radiation

Abstract

The aim of the present study is to investigate the boundary layer flow of power-law fluid over the horizontal stretching cylinder. The temperature-dependent thermal conductivity of the power-law fluid is considered. Combined effects of constant thermal conductivity and viscous dissipation are analyzed in heat transfer. The relevant boundary layer partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) by using suitable transformations. These nonlinear ordinary differential equations are solved by the BVP4C method using MATLAB. The accuracy of computed results is checked by comparing them with existing literature. To discuss the effects of flow parameters on velocity and temperature profiles graphs with numeric values are developed. The constant thermal conductivity and radiation effects are enhanced corresponding to a higher fluid temperature. The thermal boundary layer thickness is enhanced with the increase in Eckert number. The effect of all physical parameters on skin friction coefficient and local Nusselt number are discussed through tables and graphs.
