Bioconvection study of MHD hybrid nanofluid flow along a linear stretching sheet with Buoyancy effects: Local Non-Similarity Method

Abstract

Nanoparticle dispersion in aqueous solutions is a remarkable scientific technique with the potential to significantly advance many branches of engineering. This is attributed to the nonsimilar thermophysical characteristics exhibited by nanofluids in contrast to conventional fluids. The current investigation explores characteristics of bioconvective magnetohydrodynamic (MHD) flow containing suspended hybrid nanoparticles of Cu–MgO, passing through an extending porous surface. Radiation, heat generation, viscous dissipation and buoyancy influences are physical elements considered in this investigation. Additionally, the incorporation of microorganisms results in heightened fluid stability. Furthermore, Lorentz force’s influence on the fluid flow is considered. Water is considered as the base fluid. Copper and Magnesium Oxide are suspended in water. Employing a local non-similarity (LNS) transformation, PDEs are simplified to produce an ODE system. Subsequently, the system’s numerical solution for discrete values of the governing parameters is carried out utilizing the MATLAB function “bvp4c”. The obtained results exhibit a strong agreement with previously published findings. The effects of physical factors have been explored through a comprehensive parametric investigation. Mutual effects are shown through graphical representations, whereas numerical comparisons are shown through tabular displays.
