MHD tangent hyperbolic nanofluid with chemical reaction, viscous dissipation and Joule heating effects

Abstract

In this article, the motion of a non-Newtonian tangent hyperbolic nanofluid past a stretching sheet is analyzed. Nanofluid is comprised of thermophoresis and Brownian motion effects. Magnetic field is implemented in vertical direction under the assumption of low magnetic Reynolds number. The phenomenon of heat transfer has been examined subject to the viscous dissipation and Joule heating whereas the mass transfer has been analyzed under the effect of chemical reaction. The partial differential equations (PDEs) governing the flow, heat and mass transport are re-framed in the form ordinary differential equations (ODEs) by means of the similarity solutions. A numerical procedure known as the Keller-box method has been implemented to obtain the solutions for the accomplished ODEs. The effects of the variations of different involved parameters on fluid temperature, velocity and concentration distributions are disclosed through graphs and analyzed in detail. The features of skin friction, heat and mass transfer coefficient are tabulated and graphed in order to perceive the flow, heat and mass transport processes. It is noticed that an increment in the Weissenberg number results in a reduction in the velocity field.

Heat and mass transfer analysis in unsteady flow of tangent hyperbolic nanofluid over a moving wedge with buoyancy and dissipation effects

“…For instance, the recent studies of Haile and Awgichew [3] revealed that the increase in hydrodynamic slip reduces the velocity of the nanofluid; but it enhances the temperature and nanoparticle volume fraction. Some other studies on boundary layer flow of nanofluids are also indicated in the cited articles [4,5,6,7,8,9,10].…”

“…They also pointed out that the ability of the fluid on the drag based both on the physical parameters and the geometry of the proposed system. Several important researches regarding the topic of nanoliquids flow and heat mass transfer have been reported [32][33][34][35][36][37][38].…”

A Numerical Approach for an Unsteady Tangent Hyperbolic Nanofluid Flow past a Wedge in the Presence of Suction/Injection

“…Prabhakar et al [5] studied the effects of inclined Lorentz forces for zero normal fluxes of nanoparticles at the stretching sheet. A brief study on BL tangent hyperbolic flow of nanofluid is explained in these articles [6][7][8][9][10][11][12][13][14][15][16][17]. Fluids in which viscosity remain constant, no matter the shear applied on the fluid with constant temperature, e.g, water, air, gasoline, and alcohol On the other hand, non-Newtonian fluids are the fluids in which when stresses applied, viscosity will be changed, for example, quicksand, cornflour-water, silly putty, ketchup, cream, paint, glue, detergents, and molten plastics.…”
