Nonlinear mixed convection flow of a tangent hyperbolic fluid with activation energy

Abstract

In this communication, the dynamics of a non‐Newtonian tangent hyperbolic fluid with nanoparticles past a nonuniformly thickened stretching surface is discussed. We examine the impact of nonlinear mixed convection flow of a hyperbolic tangent fluid with the Cattaneo‐Christov heat and mass diffusion model past a bidirectional stretching surface. The effects of activation energy and magnetic field are incorporated in the analysis. The variables of transformations are used to change the nonlinear partial differential equations into ordinary differential equations (ODEs). Then, these ODEs are numerically solved using the Matlab routine of the bvp4c algorithm. The derailed analysis of the influences of the governing parameters on velocities along the x‐ and y‐axes, temperature and concentration profiles are presented using tables and figures. The outcomes of these parameters reveal that the velocities along the x‐ and y‐axes are decreased for the values of We increasing but the opposite behavior is observed as the value of A increases. The results also show that the values of e and N b rise as the temperature profiles increase. Similar influences are observed on the profile of concentration as the values of F and f rise. As the values of N 1 go from 0.27 to 0.25, the skin‐friction coefficient increases, and similarly, as N b goes from 0.3 to 0.1, − θ false′ false( 0 false) is enhanced.

Nonlinear convection flow of dissipative Casson nanofluid through an inclined annular microchannel with a porous medium

“…The MHD Oldroyd 8‐constant fluid flow between vertical plates with chemical reaction was examined by Yusuf et al, 25 who revealed that enhancement in magnetic field strength undermines the flow velocity, temperature, and concentration. The flow of a hyperbolic tangent fluid with the Cattaneo–Christov heat and mass diffusion through a stretching surface was reported by Ibrahim and Gizewu 26 . Hayat et al 27 presented the salient feature analysis on the flow of a thixotropic fluid in the version of the Cattaneo–Christov heat flux theory.…”

They discovered that higher values of mixed convection parameter lead to a decrease in the fluid temperature and boundary layer thickness.…”

“…Furthermore, behavior of incompressible magnetohydrodynamic flow tangent hyperbolic fluid with the effect of melting heat transfer in the stagnation point has been reported by Hayat et al [63], and the analysis of tangent hyperbolic material in the presence of both nanoparticles past an exponential surface with the heat, mass, and motile microorganisms transfer rate in the magnetohydrodynamic convective flow has been performed by Shafiq et al [64]. Moreover, Alaidrous et al [65] and Ibrahim and Gizewu [66,67] have studied tangent hyperbolic nanofluid past bidirectional extending surface under the application of some physical conditions such as thermal radiation, Joule heating, activation energy, and chemical reaction of high order by employing Cattaneo-Christov heat flux model. To our knowledge, no one has attempted to investigate the effect of three-dimensional thin film flow of tangent hyperbolic fluid with nonlinear mixed convection flow and entropy generation past stretching surface.…”
