Activity of Viscoelastic Nanofluid Film Sprayed on a Stretching Cylinder with Arrhenius Activation Energy and Entropy Generation

Abstract

The performance of viscoelastic nano-liquid film sprayed over a stretched cylinder is investigated. It also explores the effects of activation energy and the assessment of entropy on heat and mass flow. Similarity transformations have been used to make the governing equations dimensionless and successively resolved by a strong analytical technique homotopy analysis method (HAM). The velocity decreases with the magnetic field strength and the viscoelastic nanofluid parameters. The temperature increases with the Brownian motion parameter while it decreases with the increasing of Prandtl number, film thickness parameter and thermophoresis parameter. The concentration of nanoparticles is enhanced by the higher Reynolds number and the activation energy parameter. The film size causes increased with the spray rate in a nonlinear way. The two-dimensional case is recovered in the Reynolds number and film thickness limit values. A close agreement is reached by comparing the current with published results. The results obtained, perhaps in ideal circumstances, would be useful for the analysis and design of applications for coating.
