Variable viscosity and MHD flow in Casson fluid with Cattaneo-Christov heat flux model: Using Keller box method

This article presents a numerical investigation of MHD flow of Casson fluid model with variable viscosity towards a stretching sheet with variable thickness. Cattaneo-Christov heat flux model is used instead of Fourier's law to explore the heat transfer characteristics. The governing partial differential equations are transformed into nonlinear ordinary differential equations by using suitable similarity transformations. These equations are solved by using a numerical technique, known as Keller box method. The relevant physical parameters appearing in velocity and temperature distributions are analyzed and discussed through graphs. In order to check the accuracy of the method comparison has been made with some previous published results. (C) 2016 Karabuk University. Publishing services by Elsevier B.V.
