Magnetohydrodynamic bio‐nanoconvective Naiver slip flow of micropolar fluid in a stretchable horizontal channel

In this investigation, the foremost aim is to study the impact of a higher‐order chemical reaction and second‐order slip on the bioconvective nanoliquid flow comprising gyrotactic microorganisms between two squeezed parallel plates. The existence of magnetic strength, thermophoretic, and Brownian migration is considered to model the flow. Similarity transformations are implemented to reduce our mathematical model into a set of nonlinear ordinary differential equations along with the requisite boundary conditions. The classical Runge‐Kutta‐Fehlberg method technique is employed to avail the numerical outcomes of the aforementioned nonlinear foremost equations correlated with the relevant boundary conditions. Parametric flow discussions, like, velocity profile, thermal profile, and heat and mass transport, have been portrayed through indispensable charts and graphs. Physical quantities, like, skin friction, Nusselt number, Sherwood number, and microorganism density number, have been estimated to analyze their numerous applications. The results communicate that temperature diminishes for squeezing factor and first‐order velocity slip parameter, but augments for second‐order slip parameter. Mass transport accelerates for chemical reaction but reduces for the order of reaction. Microorganism density number amplifies owing to chemical reaction and Peclet number while it decays for chemical reaction. This has advantageous applications in bio‐micro‐systems, bioreactors, biosensors, biochromatography, magnetic bioseparation devices, biocoating, and ecological fuels.

This study deals with the quartic autocatalysis of homogeneous–heterogeneous chemical reaction that occurs in the bioconvective flow of micropolar nanofluid between two horizontally parallel plates. The quartic autocatalysis is found to be more effective than cubic autocatalysis since the concentration of the homogeneous species is substantially high. The upper plate is assumed to be in motion and the lower plate is kept stationary. Such a flow of micropolar fluid finds application in the pharmaceutical industry, microbial enhanced oil recovery, hydrodynamical machines, chemical processing, and so forth. The governing equations for this flow are in the form of the partial differential equation and their corresponding similarity transformation is obtained through Lie group analysis. The governing equations are further transformed to coupled nonlinear differential equations that are linearized through the Successive linearization method and are solved using the Chebyshev Collocation method. The effects of various parameters, such as micropolar coupling parameter, spin gradient parameter, reaction rates, and so forth, are analyzed. It is observed that the fluid flows with a greater velocity away from the channel walls, whereas near the channel walls the velocity decreases with an increase in the coupling parameter. Furthermore, the spin parameter increases the spin gradient viscosity that reduces the microrotation of particles that further decreases the microrotation profile.

A nanofluid is treated as a smart fluid that is useful for heat transfer enhancement, which is paramount in several industrial applications, transportation, biomedical as well as electronics. This is due to the enhanced thermophysical properties, such as Brownian motion and thermal conductivity of the suspended nanoparticles in the base fluid. The present investigation explores an electrically conducting flow of a water‐based nanofluid past a thin film placed horizontally. In particular, the Al2O3 nanoparticle is merged into the water for the preparation of the nanofluid. For the enhancement in heat transfer properties, the Brownian thermal conductivity based on the Koo‐Kleinstreuer‐Li model is introduced. The Adomian decomposition method, a semi‐analytical technique, is employed to handle the system of ordinary differential equations. The originality of the current investigation is the statistical analysis of the various characterizing parameters governing the flow phenomena. The influences of these physical parameters on the flow phenomena are displayed in graphs and tables. The major findings of the outcomes are listed as follows: an increase in particle diameter decreases the Brownian conductivity, whereas fluid temperature enhances it significantly. Also, the increase in volume concentration leads to a decrease in the fluid temperature, resulting in faster cooling processes for the production of materials in industries.
