Abstract
The thesis is mainly concerned with study of the dynamics of incompressible viscous fluids. The considered fluids are non-Newtonian and Newtonian the presence of the effect of porosity property. The considered fluids are moving in the presence of external forces. such as, the gravitational field, or the electric field or the magnetic field. The mathematical modeling and simulation of the flow of fluid in the presence of the porosity effect, are important, in many areas , including petroleum engineering, soil science and environmental engineering and in many other processes as well. Our interest is to examine the stability of viscous (and viscoelastic) fluids ill the presence of the porosity effect under influence of magnetic (or electric ) fields on the interfaces separating fluids. This thesis is divided into five chapters.
