Energy dissipative MHD Cu-AA7072/water-based hybrid nanofluid flow over a perpetually moving slender needle

Abstract

Right now, numerous nanoparticles are available in literature amidst these Copper, Aluminium and their alloys are sole feature nanoparticles with high physical, thermal and chemical possessions. These are enormously utilized in aircraft parts, generating space crafts and production of rocket climbing frames etc. This paper describes the steady and two-dimensional magnetohydrodynamic boundary layer flow of a hybrid nanofluid past a moving slandering needle. Copper (Cu) and Alumina Alloy (AA7072) are used as hybrid nanoparticles by considering water, a base fluid. The fundamental partial differential equations are transfigured to a set of nonlinear ordinary differential equations, then numerically solved with the help of MATLAB solver (bvp4c). The profiles of velocity, temperature and physical variables like skin friction coefficient and the local Nusselt number are displayed through figures for various parameters. The results are explored with nanofluid (Water + AA7072, Water + Cu) and hybrid nanofluid (Water + Cu + AA7072). The highest heat transfer rate can perceive in the case of Copper nanoparticles than AA7072 and hybrid cases (Water + Cu + AA7072) whereas skin friction is more in the case of Water + AA7072.
