MHD Stagnation Point Flow of a Casson Nanofluid Towards a Radially Stretching Disk with Convective Boundary Condition in the Presence of Heat Source/Sink

This article deals the study of effects of convective condition on MHD stagnation point Casson nanofluid flow due to radially stretching disk. The system of partial differential equations governs the flow that transformed into the nonlinear ordinary differential equations by employing suitable similarity transformations. The resulting system of ODE's is successfully solved numerically by Runge-Kutta fourth order method along with shooting technique. The effects of various emerging parameters on velocity, temperature and concentration profile are discussed in detail and presented through graphically. Velocity profile decreases by increasing Hartman number and Casson fluid parameter. Nanoparticle concentration increases with increasing thermophoresis parameter, but reverse trend is observed with the effect of Brownian motion parameter.
