Computational Investigations of Arrhenius Activation Energy and Entropy Generation in A Viscoelastic Nanofluid Flow Thin Film Sprayed on A Stretching Cylinder

Abstract

This paper investigates the two-dimensional and incompressible flow of viscoelastic nano-liquid dynamic and axisymmetric sprayed thin film deposit on a stretched cylinder. It also looked at how activation energy and entropy evaluation affected mass and heat flow. The governing equations are transformed into nonlinear ordinary differential equations using similarity transformation techniques, which are then resolved successively using a strong semi analytical homotopy analysis method (HAM). The velocity decreases as the magnetic field strength and viscoelastic parameters are increased. The temperature rises as the Brownian motion parameter increases, while it falls as the Prandtl number, film thickness parameter, and thermophoresis parameter increase. The greater the Reynolds number and the activation energy parameter, the higher the concentration of nanoparticles. The film size increases nonlinearly with the spray rate. Entropy generation increases as the Brinkmann number, magnetic field, and thermal radiation parameters increase. A nearby agreement is signed after comparing current investigation with published results. The results obtained, possibly under ideal conditions, could be useful for determining and architecting coating applications.
