The present work focuses on the flow of an incompressible, viscous nanofluid between convergent/divergent channels. Applications in cosmetics, food processing, and medicines need an understanding of interfacial layer features, which is crucial in fields like emulsions, colloid science, and surface chemistry. In view of this, the current work explores the effects of the interfacial layer and nanoparticle diameter on thermal conductivity, pollutant discharge concentration, and viscous dissipation on nanofluid flow between divergent/convergent channels. The modelled partial differential equations (PDEs) with suitable boundary conditions (BC) are changed into ordinary differential equations (ODEs) using similarity transformations. Additionally, the Galerkin finite element scheme is applied to solve ODEs and related reduced BC. Graphs are used to describe the influence of various non-dimensional factors identified in the motion equation on the velocity, temperature, and concentration profiles. In convergent/divergent channels, an increment in Reynolds number causes a reduction in concentration. The external source variation parameter and the local pollutant external source variation parameter will both escalate the concentration. The concentration of the nanofluid drops in the convergent channel and increases in the divergent channel for an increase in Schmidt number values. |
