Model development for thermodynamical analysis of convectively heated radiative and magnetized flow of ferromagnetic nanoparticles with oxytactic moment of microorganisms

Abstract

With the advancements in the field of nanotechnology the research on innovative type of fluid termed as nanofluids took attention of investigators because of its remarkable properties and usages in science as well as engineering. Since there are wide range of applications of nanofluids in different fields of life so this topic got much attention of researchers. A special feature of these fluids is environmental friendliness. Some prominent applications of nanofluid are found in the field of solar systems for improvement in efficiencies, industrial manufacturing procedures, thermal engineering along with cooling mechanisms like coolants in engines etc. Basic purpose of recent research is communication of magnetic effects in two dimensional Eyring Powell fluid models with the consideration of wide range of bioconvection as well nanofluid applications. The important properties of important physical parameters mainly Prandtl number, Magnetic interaction parameter, Eckert number, thermophoretic and Brownian motion parameter, while convectively heated surface with thermal gradient is also under consideration. The non-linear systems of PDEs are then converted into coupled nonlinear ODEs by use of appropriate similarity variables. It is observed that velocity of Eyring Powell fluid declined for increment in magnetic parameter, while temperature gradient increased with escalation in Eckert number. The density of motile microorganisms shown dwindling behavior for augmentation in estimation of Peclet number and Biot number.
