Solar radiation-driven MHD Maxwell nanofluid flow with gyrotactic microorganisms and Soret–Dufour effects: A thermal engineering study

Background

In recent progress the fluid with bio-magnetic is biotic fluid that occurs in existing mortals under magnetic field impact. Plasma is the best specimen of a bio-magnetic fluid. The studies on bio-magnetic fluid in the former limited spans, have established extra devotion from scientists, because of its significant uses in medicinal disciplines and bio-engineering, for instance dipping blood loss in operations, in magnetic stratagem expansion for cell parting and the battered remedies transport. Furthermore, magnetic particles are utilized for MRI (magnetic resonance imaging) of detailed materials of the cancer treatment or human structure.

Objective

This work elaborates the combine influences of variable conductivity and soret-doufour aspects on bioconvection magnetite Maxwell nanofluid with motile microorganism along a stretching cylinder. The impact of heat source/sink with chemical reaction is also considered in this scientific modeling in stagnation reagion. The theoretically study describes the Brownian motion and thermophoretic dispersal thought exhausting Buongiorno model.

Methodology

The homotopic tactic describes a broad uses of nonlinear problems in physics, production and applied mathematics. The suitable scaling conversions are subjugated to alter the partial differential (PDEs) into ordinary differential equations (ODEs). The homotopic analysis tactic is a semi-analytical process which is exploited for solutions of ODEs by forming a series solution constructed on the thought of homotopy.

Major findings

The outstanding physical features of flow factors on temperature, concentration and microbe concentration fields are observed and clarified tabular and graphical shape. The various physical influences performance of heat transport and density of the motile microbes are also presented. The doufour and variable conductivity factors raise the temperature field. The work exposes that the thermophoretic dispersion and Soret factors exaggerate the concentration field, whereas diminish for Brownian factor. Furthermore, the picture specifies that the growing of Peclet factor falloff the motile density field of microbe. The modern theoretic exertion has been utilized to intensify the performance of thermal energy, industrial and heat transport.
