Modeling of modified Eyring-Powell nanofluid flow subject to thermal-solutal stratification phenomenon

Population growth and rapid industrialization have led to many serious problems such as change in climate, fossil fuel shortages, crisis of energy, and environmental issues, which have become the primary risks for the survival of human being on this planet, to overcome these problems researchers take keen interest in nanofluid because they have a higher thermal conductivity than conventional base fluids, and thus can serve as an effective heat transfer medium. In present article, the impact of magnetized flow for modified Eyring-Powell fluid under thermophoretic and Brownian movements aspects is examined. Double stratification phenomenon for heat/mass transportation analyses is introduced. Some suitable similarity transformations are exploited to achieve the non-linear ODEs. The acquired ODEs are resolved numerically by using bvp4c technique. Moreover, physical elucidation for dimensionless variable's is presented. Velocity of modified Eyring-Powell nanofluid has opposite behaviors versus magnetic parameter and fluid parameter. Augmented values of radiation parameter, thermophoresis, thermal Biot number, and magnetic parameters intensify the temperature of nanofluid. More specifically, concentration of nanofluid dwindles against larger solutal Biot number and Brownian moment parameter. Transportation rate of heat intesifies for larger Pr .

Automated summary

Population growth and industrialization have caused serious problems such as climate change, fossil fuel shortages, energy crisis, and environmental issues, which are the main risks for human survival. Researchers are interested in nanofluids as they have higher thermal conductivity and can be effective heat transfer mediums. This article examines the impact of magnetized flow on modified Eyring-Powell nanofluids, and introduces a double stratification phenomenon for heat and mass transportation analysis. The obtained results show that the velocity of the nanofluid has opposite behaviors based on the magnetic and fluid parameters, and the temperature of the nanofluid is intensified by certain parameters such as radiation, thermophoresis, thermal Biot number, and magnetic parameters. The concentration of the nanofluid decreases with larger solutal Biot number and Brownian moment parameter, while the heat transportation rate increases with larger Pr.
