Abstract
This article aims to investigate the dynamics of bioconvection in metal oxide nanofluids containing microorganisms. The novelty of this article is the numerical investigation of magnetohydrodynamic (MHD) flow through parallel squeezing plates with density slip. The study employs water as the base fluid, incorporating nontoxic nanoparticles (NPs), such as copper oxide, alumina, and iron oxide. Copper oxide NPs have inhibited the growth of cervical carcinoma cells by generating reactive oxygen species. Alumina NPs are used as cosmetic fillers and integrated circuit baseboards. Iron oxide NPs increase the iron levels in tumors, which can lead to oxidative damage and tumor regression. The mathematical formulation leaves a set of coupled nonlinear ordinary differential equations of fourth-order. The equations are solved numerically using the Runge–Kutta (RK) fourth-order method associated with the shooting technique. An analysis is carried out for a wide range of control parameters, and the results are analyzed using graphs. A temperature increase is found when the plates converge, which is predominant in Iron oxide–water nanofluids compared to other nanofluids. The study also reveals that the motile flux increases with increasing squeezing number and the slip parameter, due to an increase in shear stress whenever the upper plate moves away from the lower plate.
