Thermophysical properties of chemotactic microorganisms in bio-convective peristaltic rheology of nano-liquid with slippage, Joule heating and viscous dissipation

Abstract

Credibility of numerical results for peristaltic mechanism of conductive nanofluid flowing through an asymmetric channel is evaluated sponsoring heat and mass transfer mechanism. The phenomenon of non-magnetic chemotactic microorganisms is employed to increase the stability of nanofluid. The fluid behavior is affected by wall slip and convective boundary conditions along with magnetic field. The impacts of Joule heating, viscous dissipation, thermal radiations, Brownian and thermophoresis motion are treated as well. The model is used as a computationally efficient design tool to obtain the system of nonlinear partial differential equations which is then fabricated by means of zero wave number and creeping Stokesian approach. Dimensionless governing model is solved numerically by Runge-Kutta 4 method and the outcomes are interpreted graphically. Moreover, tables and bar-charts are displayed for deep physical insight. Finite Considerable role of viscous dissipation in diffusion of momentum of the wall and entropy generation in system is observed. Moreover, Bi1 and ω1 show dominant influence on Be while η1 has no affect.
