Abstract

Of concern in this work is an investigation of the heat and mass transfer mechanisms in the presence of first-order chemical reaction for an incompressible flow of non-Newtonian Carreau fluid model past a wedge. The hydromagnetic effects are also incorporated in the present study alongside the momentum, thermal, and solutal slips on the surface of the wedge. In addition to it, the impact of variable thermal conductivity is taken into account to explore the heat transfer characteristics of the flow field. The principal equations corresponding to the physical situation are transformed over to an arrangement of non-dimensional ordinary differential equations through local similarity variables. The numerical solutions of non-dimensional systems are acquired by enforcing fifth-order Runge–Kutta integration scheme and Newton’s method with the assistance of broadly utilized computer software MATLAB. The curiosity of present investigation is that the shear stress and the fluid velocity are substantially raised by the magnetic parameter, while the temperature and concentration profiles are decelerated. Another interesting result is that the thermal slip parameter prompts the lessening of fluid temperature together with the rate of heat transfer. Furthermore, the present computations reveal that the concentration of the chemical reaction is observed to be a decreasing function of the Schmidt number and solutal slip parameter. Moreover, the suitable validations are presented to confirm the achieved results accuracy.
