Magnetohydrodynamic (MHD) flow of Sisko fluid near the axisymmetric stagnation point towards a stretching cylinder

Abstract

This paper investigates the momentum and heat transfer, MHD mixed convection flow of Sisko fluid near the axisymmetric stagnation point towards a stretching cylinder. Suitable similarity variables are selected to transmute dimensional nonlinear system into non-dimensional nonlinear system. Large mesh size and high tolerance error is considered for the convergence analysis of the numerical scheme. Graphical evaluation is displayed in order to interrogate the intrinsic behavior of responsible parameters on concerning profiles. For better description of fluid flow numerical variation in local skin friction coefficient and local Nusselt number is scrutinized through graphs and tables. Appreciable growth is found in temperature profile whereas a decrease in velocity profile is noticed when the Hartmann number is augmented. Mixed convection and velocity ratio parameters serve to enhance the rate of heat transfer from the surface. Comparison of present work in a limiting case with data available in the literature has been made for the verification of the model.
