Application of double diffusion theories to Maxwell nanofluid under the appliance of thermal radiation and gyrotactic microorganism

Abstract

Purpose The purpose of this paper is to address the entropy analysis of the 3D flow of Maxwell nanofluid containing gyrotactic microorganism in the presence of homogeneous–heterogeneous reactions with improved heat conduction and mass diffusion models over a stretched surface. Improved models are supported out by utilizing Cattaneo–Christov heat flux and generalized Fick’s law, respectively. Design/methodology/approach Governing equations which present the given flow phenomenon are modeled in the form of PDEs by applying boundary layer analysis and then suitable makeovers are engaged to transfigure prevailing partial differential equations into a set of ordinary differential equations. Transformed equations are handled via optimal homotopy analysis process in computational tool Mathematica and also a special case of already published work is substantiated and found to be in excellent settlement. Findings The bearing of innumerable convoluted physical parameters on velocity, temperature, concentration, reaction rate, the concentration of motile microorganism and entropy generation are presented and deliberated through graphs. Moreover, the convergence of the homotopic solution is presented in tabular form which confirms the reliability of the proposed scheme. It is perceived that mounting values of the magnetic parameter and Brinkman number boosts the irreversibility analysis and Bejan number diminishes for these parameters. Moreover, the growing values of Prandtl and Schmidt numbers reduce the temperature and concentration fields, respectively. Practical implications The work contained in this paper has applications in a different industry. Originality/value The work contained in this paper is original work and it is good for the researcher in the field of applied mathematics.

“…In addition, the demonstration of velocity slip behavior and thermal slip is also a part of this context. A discussion of the entropy of the flowing of Maxwell nanoliquid in the three dimensional consisting of gyrotactic microorganisms with the influence of homogeneous and nonhomogeneous changes having the enhanced heat transfer property and models of mass conversion through a stretching sheet is presented by Sohail et al 38 Refined models are mentioned by employing the Cattaneo Christov heating flow and Fick’s law in generalized view, correspondingly. Akram et al 39 discussed vermiculation of Carreau nanoliquid with varying viscidness and heating providing device over a disposed of an endoscope.…”

“…Also, they recorded the decline in the microorganisms' field against Lewis and Peclet numbers. Some important aspects are mentioned in References [13][14][15][16][17][18] and references therein. Bhatti 19 simulated the transfer of heat in Jeffrey fluid with the suspension movement of nanoparticles called Au under the action of a magnetic field in the presence of thermal radiation using a perturbation approach.…”
