Abstract

The present study investigates theoretically the flow of water-based silver (Ag), single-walled carbon nanotubes (SWCNT) and titanium oxide (TiO2) ternary nanofluid (TNF). Moreover, this study focuses on analysing the heat transfer behaviour in the TNF flow through a channel comprising two infinitely long parallel plates. Furthermore, it is assumed that the upper plate is impermeable and in motion towards and away from the stationary lower porous plate through which injection and suction take place. Further, by employing suitable similarity transformations, the fundamental equations governing the fluid flow are transformed into non-linear ODEs along with boundary conditions. The non-linear ODEs are then approached by the homotopy perturbation method (HPM) to deduce an approximate analytic solution. Further, the results achieved by HPM are compared by developing a solution through the RK-4 method. The outcomes of this study are analysed through graphs and tables, mainly velocity and temporal profiles, and numerical values concerning the magnitude of skin friction coefficient, Nusselt number and pressure distribution corresponding to various values of the pertinent parameters involved in the study. The detailed analysis on the skin friction, Nusselt number and pressure distribution carried out in this study has significant industrial and engineering applications such as lubrication and bearing systems. From the results, it is observed that the temporal profile elevates with an increase in Prandtl number. It is also noticed that an elevation in the nanoparticle's solid volume fractions tends to elevate the magnitude of the Nusselt number.
