Dynamics of nanoparticle diameter and interfacial layer on flow of non-Newtonian (Jeffrey) nanofluid over a convective curved stretching sheet

Abstract

This study inspects the steady flow of a Jeffrey nanofluid stimulated by the linear stretching of a curved sheet. Working fluid is made up of graphene nanoparticles in a base medium of water. The heat sink/ source and convective boundary condition phenomenon highlights the heat transfer of the flow. The effect of liquid–solid interfacial layer and the nanoparticle diameter is also presented at the molecular level to illustrate the thermal integrity of the considered flow. Leading equations are numerically assessed after being transformed into dimensionless forms by using similarity transformations. To enhance the analysis part, several graphs and tables are shown. The features of a wide range of parameters are explored and discussed. The impact of these parameters on the rate of heat transport is also explored. Results reveal that the nanofluid velocity increases for curvature parameter. In addition, the heat transmission amplifies for heat source parameter and convective parameter. The rate of heat transport amplifies for curvature parameter and Biot number but deteriorates for heat source/ sink parameter.
