Magnetic force effects on peristaltic transport of hybrid bio-nanofluid (Au-Cu nanoparticles) with moderate Reynolds number: An expanding horizon

This work investigates the magnetic force and nonlinear thermal radiation on hybrid bio-nanofluid flow in a peristaltic channel under the influence of an applied magnetic field with high and low Reynolds number. Gold and copper nanoparticles are taken into account. Momentum, Maxwell, and heat with nonlinear thermal radiation and heat source think equations are considered in the dimensionless form without any approximation as a system of nonlinear partial differential equations. The expressions of velocity, induced magnetic field components, magnetic pressure, stream function, magnetic force, joule heating, shear stress, and Nusselt number have been obtained using the Adomian decomposition method. Influences of miscellaneous physical and biomedical parameters including moderate Reynolds, magnetic Reynolds, hybrid nanofluid volume fraction, Hartmann, dimensionless wavenumber, electric field stress, nonlinear thermal radiation, and internal heat generation absorption parameters on velocity, induced magnetic field components, magnetic pressure, normal component of the pressure gradient, heat distribution shear stress on the walls and Nusselt number are plotted and examined. During the investigation, it is found that the gold nanofluid has the highest velocity compared with hybrid, copper, and base fluid, while the hybrid nanofluid has a high magnetic force. The nonlinear thermal radiation is rising the heat distribution for hybrid nanofluid
