Two dimensional boundary layer flow with heat and mass transfer of magneto hydrodynamic non-Newtonian nanofluid through porous medium over a semi-infinite moving plate

摘要

Steady two-dimensional motion of an incompressible non-Newtonian Nanofluid through porous medium over a semi-infinite moving plate is studied . The system is stressed by an external uniform magnetic field. The heat and mass transfer are considered with the flow of non-Newtonian fluid which obeys the Eyring-Powell model. The problem is mathematically formulated and solved numerically using the ParametricNDSolve-Mathematica package. The effects of the physical parameters of the problem such as, permeability, chemical reaction as well as the fluid material parameters Hartmann number, Eckert number and Reynolds number are discussed and illustrated in figures with some important applications. The results show that the fluid velocity increases with the increases of porosity parameter as well as the material parameter, but it decreases with the increase of the magnetic field. Increasing the magnetic field decreases porosity, temperature and concentration. The effects of some physical quantities on fluid velocity distribution can be neglected.
