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 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 the current investigation with published results. The results obtained, possibly under ideal conditions, could be useful for determining and architecting coating applications.

Accessing the thermodynamics of Walter‐B fluid with magnetic dipole effect past a curved stretching surface

“…Kumar [9] considered the magnetic dipole on the water base nanofluid past a stretching sheet who showed that skin friction and Nusselt number are reduced by increasing the second-grade fluid parameter. Related studies can be seen in the references [10][11][12][13][14][15][16][17][18]. Heat transfer has important applications in industries which is directly related to production cost.…”

Enhanced heat transmission in hydrodynamic Maxwell and Jeffrey cylindrical film flows: A computational numerical simulation

“…A stochastic process to study the hydrodynamic border layer flow concluded an expanding surface was mathematically exemplified by Ullah et al 17 The researchers theoretically examined the tinny film flow of non-Newtonian solutions in the attendance of radiative and dissipative heats. [18][19][20] The role of nanospray on heat transmission enhancement of the hydrodynamic flow above a cylinder was mathematically scrutinized by Khan et al 21 The above work is extended by Usman et al 22 by considering the viscoelastic flow. In this study, they evaluated the entropy and activation energy.…”
