Impact of Homogeneous‐Heterogeneous Reactions on Flow of Non‐Newtonian Ferrofluid over a Stretching Sheet

Abstract

In this study, we considered heterogeneous and homogeneous chemical reactions in Eyring-Powell ferrofluid past a stretchable surface. In addition, thermal radiation and magnetic dipole impacts are also considered. The direct numerical solution of the governing model is complex. For this, we simplified the model into coupled ordinary differential equations (ODEs) with the dimensionless variables. Then, we determined the computational solution of the resulting transformed ODE system via the Runge-Kutta (RK) method. The impacts of interesting engineering parameters on temperature, velocity, and concatenation behaviors are presented through graphs. We concluded that the velocity field is reduced for higher values of ferromagnetic parameter β and fluid material parameters ß and H and arises the temperature field for higher values of thermal radiation R while the temperature field is reduced for Prandtl number Pr and dissipation parameter λ 1 . The obtained results of the current work are compared with published work, and we found that between them a good agreement can be seen in the table. The characteristics of skin fraction and Nusselt number are presented.

Non‐Darcy‐Forchheimer flow of Casson‐Williamson nanofluid on melting curved stretching sheet influenced by magnetic dipole

“…Time‐dependent flow in a stretching surface has been shown to be affected by homo‐heterogenic interactions, as shown by the work of Zeb et al. [24]. For increasing both homogeneous and heterogeneous reaction parameters, the concentration distribution has decreased.…”

“…Waini et al 22 has investigated hybrid nanofluid flow with homogeneous and heterogeneous chemical reactions. Zeb et al 23 has calculated the consequences of homogeneous heterogeneous chemical reactions on flow of non-Newtonian ferrofluid toward a stretching sheet. Effects of homogeneous and heterogeneous chemical reactions on motion of Casson nanoliquid due to curved oscillatory sheet were analyzed by Abbas et al 24 Upreti et al 25 has investigated the homogeneous–heterogeneous reactions effects in sisko nanofluid flow past across convectively heated stretching sheet.…”

Hybrid Methodology for the Computational Behaviour of Thermal Radiation and Chemical Reaction on Viscoelastic Nanofluid Flow

“…Furthermore, streamlines and isotherms have been evaluated for the multiple parametric values. Zeb et al [31] deliberated the Eyring-Powel ferrofluid with the addition of thermal radiative effect and magnetic dipole along with chemical reaction subjected to heterogeneous and homogeneous situations over a stretchable surface computed via the Runge-Kutta method with shooting procedure. Javid et al [32] examined the physical impacts of electro-osmosis and magnetic fields embedded in porosity and thermal slip-on flow on nanofluid via an asymmetric microchannel accomplished with convective boundary conditions.…”
