The present study emphases steady boundary layer flow and heat transfer of a hyperbolic tangent fluid flowing over a vertical exponentially stretching cylinder in its axial directionwith non-uniform heat source/sink. Proposed mathematical model has a tendency to characterize the effect of the non-uniform heat source/sink. The non-linear ordinary differential equations are solved using the Runge-Kutta Feldberg (RKF) integration method. The characteristics of velocity and temperature boundary layers in the presence of Weissennberg number We are presented for different physical parameters such as heat source/ sink parameter, Reynolds number Re, the Prandtl number Pr , the Weissennberg number We and the natural convection parameter λ , magnetic field parameter and porosity parameter K . Moreover, the friction factor coefficients, Nusselt number are also estimated and discussed for aforesaid physical parameters. In addition, the rate of heat transfer rate is higher in case of We = 0.5 compared toWe = 0 with n = 0.2 .#### Keywords
