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

Abstract

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 [Formula: see text].
