Abstract
The problem of magneto-hydro-dynamic (MHD) mass and heat transfer of an oscillatory fluid in two-dimensional viscous, electrically conducting over an infinite vertical permeable moving plate in a saturated porous medium with the presence of a transverse magnetic field and chemical reaction is analytically presented. The governing equations, momentum, energy, and concentration are solved. Various flow parameters effects on velocity, temperature and concentration fields are discussed. It is found that, the fluid velocity increases with increasing both the permeability and chemical reaction parameters. While, it increases with decreasing the magnetic field parameter. Furthermore, the concentration increases with increasing chemical reaction parameters.
Highlights
The study of the area of (MHD) mass and heat transfer problems combined with chemical reaction in the presence of magnetic field through porous medium has importance in many practical applications in the areas of engineering and science
Analytical solution for the problem of mass and heat transfer of an electrically conducting, heat generation/absorption, Newtonian, laminar, and viscous flow fluid on a continuously vertical permeable surface with the presence of a radiation, Vajravelu (1986) [2], studied the exact solutions of heat transfer and hydro-magnetic boundary-layer flow over a moving continuous flat surface with internal heat generation/absorption and uniform suction, this type of flow represents a new class of boundary-layer problems, with substantially solutions different from those for boundary layer flow on a finite length flat surface
Ahmed and Das (2013) [7], presented the effects of chemical reaction and thermal radiation on unsteady MHD mass transfer flow past a semi-infinite vertical porous plate, which is embedded in porous medium in a slip flow regime with variable suction
Summary
The study of the area of (MHD) mass and heat transfer problems combined with chemical reaction in the presence of magnetic field through porous medium has importance in many practical applications in the areas of engineering and science This phenomenon plays a very important role in many science and technology branches such as chemical industry, geothermal system, nuclear reactors cooling, petroleum industry, and packed-bed catalytic reactors. Muthucumaraswamy (2001) [8], presented a finite-difference solution of the transient natural convection flow of a viscous incompressible fluid past an impulsively started semi-infinite plate with uniform heat and mass flux, in the presence of homogeneous chemical reaction of the first order. Khadrawi and Al-Odat (2005) [14], studied analytically the transient MHD free convection flows over a semi-infinite moving vertical permeable flat plate embedded a porous medium with uniform suction using the Laplace transformation technique. The effects of several flow parameters on the thermal and hydrodynamics behavior will be analyzed
