ABSTRAKT

The present analysis deals with steady two-dimensional oblique stagnation-point flow of an incompressible Casson fluid with variable viscosity. The variation of viscosity is expressed as an exponential function of temperature. Using the scaling group of transformations, the governing partial differential equations are transformed into a set of nonlinear coupled ordinary differential equations which are solved numerically via the fourth-order Runge-Kutta-Fehlberg scheme coupled with a shooting technique. Variations of diverse parameters on normal, tangential velocity profiles, and temperature are expressed by graphs. The physical quantities of interest such as skin friction coefficients and local heat flux are investigated numerically. Streamline patterns are portrayed to visualize the actual flow behavior against various parameters. It is found that the viscosity variation parameter has increasing effects on the tangential velocity profile (near the wall), temperature distribution, and normal skin friction coefficient, while the normal velocity profile and tangential skin friction coefficient decrease with viscosity parameter.
