Abstract

The convective-radiative magnetohydrodynamic non-Newtonian second grade fluid
boundary layer flow from a curved stretching surface has been scrutinized in the present study.
The Reiner-Rivlin second grade viscoelastic model is deployed which provides a good
approximation for certain magnetic polymers. High temperature invokes the presence of
radiative heat transfer which is simulated with the Rosseland diffusion approximation. Viscous
dissipation and Joule heating are also featured in the model and hydrodynamic (velocity) slip
at the wall is also incorporated in the boundary conditions. The emerging nonlinear coupled
dimensionless transport equations are solved with a Runge-Kutta method and a shooting
numerical scheme. The influence of emerging multi-physical flow parameters on the
dimensionless profiles are examined with the help of plots for comparative analysis of both
non-Newtonian fluid and Newtonian fluid. The numerical solutions are validated for special
cases with existing works. The velocity declines for higher magnetic field whereas the reverse
trend is noted for the temperature function. An augmentation in thermal field is noted with
increment in radiation parameter. Furthermore, the fluid temperature of second grade fluid is
higher with increasing Brinkmann number. Wall slip induces deceleration. Contour plots for
streamlines and isotherms are also visualized and analyzed.
