Consequence of flow and heat transfer analysis in a quadratic mixed convection magneto-micropolar nanofluid induced by an expanded stretching

This specific study investigates the flow and heat transfer analysis in a quadratic mixed convection magneto-micropolar nanofluid over a vertically stretched sheet. The electro-conducting reactive micropolar fluid contains tiny nanoparticles in the presence of viscous dissipation, Joulean heating, Brownian movement of microscopic particles, thermal radiation, thermo-migration of particles, and prescribed surface temperature. Appropriate similarity variables are imposed on the mathematical equations to transform the partial derivatives governing the flow equations into ordinary derivatives, allowing for the numerical solution through the Runge-Kutta Fehlberg technique alongside shooting method. The parametric analysis of the physical quantities on the transport fields are illustrated by means of graphs while the findings show that an increase in the magnetic field term decelerates the velocity profiles of the micropolar fluid nanofluid while simultaneously reducing the thickness of the boundary layer of momentum. Furthermore, the concentration field of the nanoparticles profile decreases when the chemical reaction and Brownian motion parameters escalate whereas thermal radiation term raises the heat distribution across the surface.
