Abstract

The objective of this paper is to study the effect of non-constant 2-dimensional free convective flow during the motion of a viscous incompressible dusty fluid through a highly porous medium. The porous medium is bounded by a vertical plane surface of constant temperature. The surface absorbs the dusty fluid with constant velocity and the free stream velocity of the fluid vibrates about a mean constant value. Analytical expressions for the velocity of the fluid and dust are given. The effects of Grashof number and permeability parameter upon the velocity field are also shown in a graphical representation. The velocity profiles decreases with an increase in the mass concentration of the dust particles (or) increase of frequency parameter (or) increase of permeability parameter (or) increase of Grashof number.
