Abstract
The natural convective flow and associated heat transfer in a fluid saturat ed porous medium have been investigated using the generalised porous medium approach. Many new features have been predicted with the convective heal t ransfer boundary condition. A detailed parametric study reveals that multic ellular flow patterns appear at higher Darcy and Rayleigh numbers and lower Biot numbers. Results are: presented for a Darcy number range of 10(-7) 10 (-2), Rayleigh number range of 10(2)-10(9) and aspect ratios from 1 to 10. (C) 1998 Elsevier Science Ltd. All rights reserved.
