M. Grundmann et al., ASYMPTOTIC SOLUTION OF NATURAL-CONVECTION PROBLEM IN A SQUARE CAVITY HEATED FROM BELOW, INTERNATIONAL JOURNAL OF NUMERICAL METHODS FOR HEAT & FLUID FLOW, 6(5), 1996, pp. 29-36
Studies a two-dimensional natural convection in a porous, square cavit
y using a regular asymptotic development in powers of the Rayleigh num
ber. Carries the approximation through to the 34th order. Analyses con
vergence of the resulting series for the Nusselt number in both monoce
llular and multicellular cases, providing insight in the validity regi
ons of the power series.
