Numerical communication for MHD thermally stratified dual convection flow of Casson fluid yields by stretching cylinder

摘要

This work reports the comparative study of magnetohydrodynamic mixed convection boundary layer flow of Casson fluid brought by both flat and cylindrical stretching surfaces. Flow field analysis is accounted with thermal stratification phenomena. The temperature is assumed to be higher across the surface of cylinder as compared to ambient fluid. The arising mathematically modelled partial differential equations of Casson fluid flow are successfully converted into ordinary differential equations with the source of suitable transformation. The numerical solutions are computed through the application of shooting technique charted with fifth order Runge-Kutta algorithm. The effect logs of an interesting physical parameters namely, magnetic field parameter, mixed convection parameter, thermal stratification parameter, heat generation parameter, curvature parameter and Prandtl number are discussed graphically. Further, the variations of skin friction coefficient and heat transfer rate are identified by way of tables. (C) 2017 The Physical Society of the Republic of China (Taiwan).
