Thin Film Flow of Tangent Hyperbolic Fluid with Nonlinear Mixed Convection Flow and Entropy Generation

Abstract

This paper examined the three-dimensional steady thin film flow of tangent hyperbolic fluid with nonlinear mixed convection flow and entropy generation past a stretching surface under the influence of magnetic field. For the flow problem, the Cattaneo–Christov heat and mass diffusion model was employed to examine heat and mass transfer characteristics and impacts of the normally directed magnetic field. To transform nonlinear PDEs into ODEs, the variable transformation technique was used. The bvp4c algorithm was implemented to solve these ODEs. The behavior of every leading parameter on the velocities, temperature, concentration profile, entropy generation, and Bejan number was reported with tabular and figurative form. The results show that as the values of Br increase, the entropy generation enhances, but the Bejan number decreases. Moreover, as the values of B increase, the opposite characteristics are observed in entropy generation and Bejan number graphs. Furthermore, the skin friction coefficient number, local Nusselt number, and Sherwood number are graphically discussed for the active involved parameters. The best agreement is recorded when we compare this paper with the previous literature for various values of M .

Numerical analysis for tangent-hyperbolic micropolar nanofluid flow over an extending layer through a permeable medium

“…The present model illustrates a non-Newtonian laminar hydrodynamic two-dimensional nanofluid movement in the neighborhood of a broadening surface, and obeys the tangent hyperbolic prototype 31 and 32 . The novelty of this work lies in identifying and modeling the thermal and volumetric nanoparticle distributions of the tangent hyperbolic micro rotating liquid across an extending layer.…”

“…1 . Therefore, the stretching surface is located at , which stretches along with the path with a steadily stretched parameter, see 31 and 33 . The flow is supposed to be restricted to the boundary layer region , which is adjacent to the linear spreading border through a permeable medium with permeability .…”

“…For the purpose of simplicity, the influence of electric strength can be overlooked. The non-existence of the induced magnetic intensity is produced by the hypothesis of a small Reynolds numeral 31 and 32 . Because of the presence of the Lorenz force, the fluid is magnetized.…”

Stability analysis of dual solutions for mixed convection and thermal radiation with hybrid nanofluid flow past shrinking/stretching curved surface

“…Gohar et al 24 explored the influence of mixed convection flow in Casson hybrid nanofluid under a curved past stretching sheet on the contribution, according to Darcy-Forchheimer, of permeable media in an incompressible viscous fluid flow. Ibrahim and Gizewu 25 – 27 examine mixed convection flow with modified Fick’s and Fourier’s diffusion theories of non-Newtonian tangent hyperbolic fluid in the presence of convective and slip boundary conditions past the non-uniform thickness, bi-directional stretching sheet and entropy generation under a thin film flow boundary condition.…”

Dual Stratification Effects on Mixed Convective Electro-magnetohydrodynamic Flow over a Stretching Plate with Multiple Slips and Cross Diffusion

“…The thermal slip parameter and the mixed convection parameter are demonstrated to have a significant impact on the wall heat transfer coefficient. Ibrahim and Gizewu [23] investigated the three-dimensional continuous thin film flow of tangent hyperbolic fluid past a stretching surface together with nonlinear mixed convection flow and entropy production. As shown in works by Yin et al [24], the literature survey reveals a number of research that explore the viability of obtaining exact solutions for specific nonlinear models.…”
