A study on heat transfer enhancement of Copper (Cu)-Ethylene glycol based nanoparticle on radial stretching sheet

Copper nanoparticles are getting attention because of their outstanding physical charac-teristics and wide range of uses. The motivation of this research is to investigate axisymmetric flow and heat transfer for various shapes (Cylinder, Platelets and Sphere) of Copper (Cu) nanoparticles on a radial stretching sheet. Energy and momentum partial differential equations are transformed into nonlinear ordinary differential equations (ODE). The dimensionless equations are solved using the BVP4C method to yield numerical solutions for the represented problem. The impacts of multi -shape Copper (Cu) nanoparticles are thoroughly examined, as are other parameters such as solid volume fraction (/), Prandtl number Pr, unsteadiness parameter S, magnetic parameter M, slip parameter k, and Eckert number EC. According to the findings, Platelet shape Copper (Cu) nanoparticles have the highest flow and Sphere shape particles contain maximum heat transfer rate.(c) 2023 THE AUTHORS.

Automated summary

This research aims to investigate the axisymmetric flow and heat transfer of different shapes (Cylinder, Platelets, and Sphere) of Copper (Cu) nanoparticles on a radial stretching sheet. By transforming the energy and momentum partial differential equations into nonlinear ordinary differential equations and solving them with the BVP4C method, numerical solutions for the problem are obtained. The impacts of various shapes of Copper (Cu) nanoparticles and other parameters are thoroughly examined, including the solid volume fraction (/), Prandtl number Pr, unsteadiness parameter S, magnetic parameter M, slip parameter k, and Eckert number EC. The findings indicate that Platelet-shaped Copper (Cu) nanoparticles exhibit the highest flow performance, while Sphere-shaped particles have the maximum heat transfer rate.
