Insight into the axisymmetric stagnation point flow of ternary nanoparticles with heat transfer across a stretchable flat surface and circular cylinder

Abstract

The present study investigates the radiative heat transmission in axisymmetric stagnation point flow of ternary nanofluid across the stretchable flat surface and circular cylinder. This analysis considers a base fluid of water suspended with three dissimilarly shaped nanoparticles: silver, multi-walled carbon nanotubes, and Graphene. To optimize thermal management systems and sophisticated cooling, it is crucial to investigate the axisymmetric stagnation point flow of ternary nanoparticles with heat transmission. Ternary nanoparticles improve heat transfer performance by increasing thermal conductivity. Designing high-performance materials and nanofluid applications is aided by understanding such flow behaviour. The mathematical model has been framed with all the above considerations resulting to the system of partial differential equations. These systems of equations are transformed into ordinary differential equations. The exact solutions are derived to the well-known particular solutions using permeable stretchable surface conditions. The flow characteristics and thermal performance of ternary nanoparticles are described by pertinent parameters and displayed through graphs. The outcomes of this investigation disclose that the enhancement in the heat transmission rate is achieved due to the collision of nanoparticles and the action of the cooled walls of both geometries due to suction.
