Asymptotic Solution of Natural Convection Problems
in a Porous Square Cavity Heated from Below.

M. Grundmann, A. Mojtabi & B. van 't Hof 1995

Abstract:
Two-dimensional natural convection in a porous,
square cavity is studied using a regular asymptotic development in powers of
the Rayleigh number. The approximation has been carried through to the 34th
order. Convergence of the resulting series for the Nusselt number has been
analyzed in both monocellular and multicellular cases, providing insight
in the validity regions of these power series.
