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.
