| Summary: | This study investigates the magnetohydrodynamic mixed convective flow of Falkner–Skan nanofluid over a stretchable unsteady wedge, with potential applications in biomedical and thermal management processes such as advanced skin patches, cooling of electronic devices and thermal regulation of batteries in EVs. The main theme of this work focuses on the need and importance for enhancing heat and mass transmission efficiencies in these and similar applications. This has been treated through actively engaging the concepts of bio-convection theory of motile microorganisms. The theoretical framework followed here integrates particle-induced convection, binary chemical reactions, slip-conditions, thermal conductivity and presence of a magnetic field. Binary processes have direct impact on heat generation and dissipation, fluid flow patterns and thermal properties. For example, depending on the specific active dynamics of such reactions heat and mass transfer rates may be either speeded-up or impeded. The governing PDEs of Falkner–Skan law model are reduced to a set of nonlinear ODEs through similarity transformations which are then integrated numerically using bvp4c-solver. The impact of the different contributing fluid parameters on velocity, temperature, volumetric concentration and concentration of microorganisms’ profiles are deliberated via literature and illustrated graphically. The outcomes reveal that enhancements in the wedge angle parameter boosts the nanofluid velocity, while opposite behavior is noted in velocity profile for growing value of magnetic parameter. Density of gyrotactic microorganisms is seen to decline with growing value of bioconvective Lewis number. Moreover, higher values of the Prandtl number lead to a decline in the temperature distribution. |
