Abstract

Numerical solutions of the full Navier-Stokes equations are obtained for the problem of natural convection in closed cavities of small aspect ratio with differentially heated end walls. These solutions cover the parameter range Pr = 6·983, 10 [less-than-or-equal] Gr 2 × 104 and 0·05 [less-than-or-eq, slant] A [less-than-or-eq, slant] 1. A comparison with the asymptotic theory of part 1 shows excellent agreement between the analytical and numerical solutions provided that A [less, similar] 0·1 and Gr2A3Pr2 [less, similar] 105. In addition, the numerical solutions demonstrate the transition between the shallow-cavity limit of part 1 and the boundary-layer limit; A fixed, Gr [rightward arrow] [infty infinity].
