Nanoparticle effect over the boundary layer flow over an exponentially stretching cylinder

This study provides an analysis of the nanoparticle effects over the steady boundary layer flow and heat transfer of viscous fluid flowing over a vertical cylinder that is stretched along its axial direction. The system of nonlinear partial differential equations associated with the problem along with the appropriate boundary conditions is nondimensionalized by means of the boundary layer estimates and invoking a suitable similarity transformation. The resulting nonlinear coupled system of ordinary differential equations subject to the appropriate boundary conditions is solved through the Runge–Kutta–Fehlberg numerical scheme. A comparison of the obtained numerical results is also presented with the help of homotopy analysis method. At the end, effects of the allied physical features for the flow, heat transfer and nanoparticle concentration profiles are also discussed.
