Characteristic of thermophoretic effect and convective thermal conditions on flow of hybrid nanofluid over a moving thin needle

Abstract

This paper presents the impact of thermophoretic particle deposition in the flow of a hybrid nanofluid (Fe3O4-Go/H2O) over a moving thin needle in the presence of a convective boundary condition. The set of non-linear partial differential equations is transformed into ordinary differential equations with the implementation of suitable transformations. Further, the numerical evaluation is carried out by employing the RKF-45 method along with the shooting procedure via the aid of Maple 17 software. It should be noted that the approval of the results shows a good correlation with the existing results. The obtained graphs mainly explain the fundamental characteristics and impacts of different constraints on hybrid nanofluid and mano nanofluid. The main outcomes bring out that enhancement of thermophoretic parameter increases the concentration field and increase in Biot number increases thermal efficiency. Also, the velocity and concentration profiles of hybrid nanofluid reduce with the increment of the magnetic parameter. But the thermal profile of hybrid nanofluid exhibits contrasting behavior.
