Impact of an inclined magnetic field on couple stress fluid flow over a stretching surface with effect of Stefan blowing, radiation and chemical reaction

Abstract

The present work focuses on the investigation of the couple stress nanofluid flow with the inclined magnetic field, heat, and mass transform effect. The impact of parameters such as the Schmidt number, the Prandtl number, the Stefan Boltzmann constant, and the magnetic field parameter is evaluated. The regular partial differential equations (PDEs) are mapped into ordinary differential equations (ODEs) and solved analytically, while the exact solution of heat and mass transfer is given in terms of confluent hypergeometric function. It is shown that the impact of the couple blowing effect has primitive impact on velocity, temperature and concentration profiles. The magnetic parameter, by posing a magnetic field normal to the stretching sheet, reduces the flow velocity, the couple stress fluid parameter increases the amplitude of oscillations in velocity and skin friction coefficient, the heat source/sink parameter increases the temperature of the fluid, the volume fraction of the nanoparticles increases the thermal efficiency of the fluid, the chemical reaction parameter decreases the temperature of the fluid, and, finally, the thermal radiation increases the nanofluid temperature.
