摘要

A numerical study has been made to analyze the effects of aniso- tropic permeability and thermal diffusivity on natural convection in a heat generating porous medium contained in a vertical cylin- drical enclosure with isothermal wall and the top and bottom perfectly insulated surfaces. The results show that the anisotropies influence the flow field and heat transfer rate significantly. The non-dimensional maximum cavity temperature increases with in- crease in permeability ratio. For aspect ratio greater than or equal to two, the nondimensional maximum cavity temperature increases with an increase in the thermal diffusivity ratio.
