- Abstract
Flow of rheological fluids often obeys stagnation flow dynamics in a number of modern-day manufacturing processes. Such flows not only invoke radiative heat transfer under high temperature but also exhibit considerable viscosity variation with temperature. Motivated by such fascinating facts, the present study is an effort to explore steady, two-dimensional crosswise transport of Casson fluid past a surface. A temperature-dependent viscosity model is incorporated along with magnetohydrodynamic effects. The conservation equations for mass, normal and tangential momentum and energy are normalized with the help of similarity transformations that are solved afterwards numerically using efficient Runge–Kutta–Fehlberg scheme with shooting quadrature in MATLAB symbolic software. Comparison with the existing published literature is also presented to validate the solutions. Results of velocity, temperature, skin friction and heat flux are presented graphically and discussed in a physical manner. Graphical outcomes indicated that normal velocity profile declined rapidly with magnetic field strength, whereas thermal radiation enhanced the temperature distribution in the fluid flow. This trend revealed that thermal performance of viscoplastic fluid flow improved when radiation effects are incorporated. It is also noted that heat transfer rate at the stretching surface dropped with radiation parameter. Normal skin friction is observed to be significantly reduced, while tangential skin friction enhances with stronger magnetic field effects.
