Analyzing numerical insights of entropy generation and existence of chemotactic microorganisms for magnetized radiative Carreau nanofluid flow subjected to stratified medium via viscous dissipation

Abstract

Owing to improved thermal characteristics along with increasing trend of nanotechnology in variety of fields including medical, aerospace technology, advanced cooling system, modern cooling devices, manufacturing of latest biodegradable plastic, pharmaceutical industry, remediation of environment, coolant in vehicles engines, MRI machines, manufacturing of efficient batteries, latest electronic technology based on nanotechnology. In recent article we have discussed the MHD flow of nanofluid along rate of entropy generation above the stretching plate. The major effects of Brownian motion along thermophoresis phenomena are also a part of our investigation. The energy generation and energy absorption are also under consideration with non-renewable resources of energy. Basic purpose of current exploration is exploration of the impacts of convective boundary condition on two dimensional MHD flow of nanofluid is considered with stratification phenomena. The effects of magnetic field are also observed with variation in temperature, concentration and entropy generation. Here shooting scheme is used with bvp4c technique to convert the system of PDEs to resultant ODEs. Different dimensionless parameters are taken in account to discuss the variation of important fluid parameters like Nusselt number and Sherwood number in tabular form. The micro-organisms profile declines with increment of Lewis number along with Peclet number. Concentration of nanofluid increases with Brownian motion while conflicting behavior is observed in case of thermophoresis parameter.
