Mixed convection flow along a vertical permeable plate embedded in a porous medium in the presence of a transverse magnetic field
- Kuwait Univ., Safat (Kuwait). Dept. of Mechanical and Industrial Engineering
Continuum boundary layer equations are derived for governing steady, laminar, hydromagnetic, mixed convection flow along a vertical semi-infinite permeable plate maintained at constant heat flux and embedded in a uniform porous medium with heat generation and magnetic dissipation. A mixed-convection parameter covering the entire range from pure forced convection to pure free convection is introduced. The governing equations are transformed using a non-similarity transformation and solved numerically by an implicit finite difference method. Typical results for the skin friction coefficient and the wall heat transfer are presented and discussed for various parametric conditions. The investigation of forced, mixed, and free convection heat transfer from surfaces embedded in porous media has received considerable attention in view of its importance in the petroleum industries, filtration, heat exchanger design, thermal insulation, chemical catalytic reactors, burying of drums containing heat-generating chemicals in the earth, and underground spread of pollutants.
