ABSTRACT: Study to analyze the MHD stagnation point flow of a Casson fluid
over a nonlinearly stretching sheet with viscous dissipation was
carried out. The partial differential equations governing this phenomenon were
transformed into coupled nonlinear ordinary differential equations with suitable
similarity transformations. These equations were then solved by finite
difference technique known as Keller Box method. The various parameters such as
Prandtl number (Pr), Eckert number (Ec), Magnetic parameter (M), Casson parameter (β) and non linear stretching parameter (n) determining the velocity and
temperature distributions, the local Skin friction coefficient and the local
Nusselt number governing such a flow were also analyzed. On analysis it was
found that the Casson fluid parameter (β)
decreased both the fluid velocity and temperature whereas an increase in (β) increased both the heat transfer rate
and wall skin-friction coefficient.
