Insights Into the Significant Impact of Endothermic/Exothermic Chemical Reaction and Hybrid Nanoparticles Induced by a Microchannel With Lorentz Forces

ABSTRACT The distinct rheological properties of Boger fluid make it useful in various scientific and engineering applications. Boger fluids are utilised in biomedical research to mimic the viscosity of biological fluids, supporting the design of medical devices and drug delivery systems. Therefore, the present work aims to scrutinise the incompressible steady flow of a Boger hybrid nanofluid through a microchannel with the influences of bioconvection, activation energy, magnetic field, endothermic/exothermic chemical reaction and Hall current. By introducing appropriate similarity variables, the nonlinear partial differential equations are reduced to ordinary differential equations. The resulting ordinary differential equations are solved by applying the Runge‐Kutta‐Fehlberg‐ fourth fifth order technique. The effects of various nondimensional constraints on their corresponding profiles can be illustrated graphically. The significant results of this study demonstrate that as the values of the solvent fraction constraint increases vertical, it leads to a drop in the velocity profile. As the ratio of the relaxation time constraint escalates, velocity enhances. Skin friction will increase as the magnetic constraint and the solid volume fraction values escalate.
