Aspects of entropy generation for the non-similar three-dimensional bioconvection flow of nanofluids

Abstract

This research work presents the entropy analysis of the three-dimensional bioconvection flow of nanofluid over a linearly moving plate in the presence of magnetic effects. Nanoparticles and microorganisms have been considered in the fluid, with the magnetic field acting in the transverse direction to the plate. The viscous dissipation term is also considered in the energy equation. The partial differential equations (PDEs) of the boundary layer region of this problem are transformed with suitable non-similarity transformations into a system of nonlinear PDEs. Afterward, the local non-similarity method via the BVP4c MATLAB algorithm with a second level of truncation delivers a solution of the problem. The effect of important parameters such as magnetic field, Eckert number, thermophoresis, Prandtl number, Peclet number, Brownian motion, Schmidt number, Brinkman number, Lewis number, slip factor on temperature distribution, concentration of nanofluid, density of motile microorganisms, and entropy generation are shown in the graphical profiles.

Nonsimilar Modeling and Numerical Simulations of Electromagnetic Radiative Flow of Nanofluid with Entropy Generation

“…Khan et al [22] evaluated the EG in nanofluid flow through porous medium comprising microorganisms and nanoparticles. Some important studies on EG have been conducted in [23][24][25][26][27][28][29].…”

Non‐similar modelling of Williamson Fluid over a non‐linear stretching sheet with temperature dependent thermal conductivity and Chemical Reactions

“…Hayat [35] also solved non-similarity flow of nanofluid and obtained a series solution. Farooq et al [36] investigated aspects of entropy for non-similar three-dimensional flow of nanofluid in presence of magnetic effect. Shukla et al [37] found a non-similar solution for non-Newtonian fluid by using a local non-similar method.…”

Magnetic field promoted irreversible process of water based nanocomposites with heat and mass transfer flow

“…Bhatti et al 34 investigated the entropy generation past a moving surface with thermal radiation and chemical reaction using successive linearization method and chebyshev spectral collocation method for the reduced resulting non-linear coupled ordinary differential equations. Farooq et al 35 presented the entropy analysis of three-dimensional bioconvection flow of nanofluid past a linearly moving plate in the presence of magnetic field and microorganisms by applying the BVP4c MATLAB algorithm. Mondal et al 36 discussed the entropy generation and provided the dual solutions with the spectral quasiliearization method for the magnetohydrodynamic three-dimensional convective flow and heat transfer in a nanofluid.…”
