珍惜眼前人的句子摘要：Results from direct numerical simulation for three-dimensional Rayleigh Benard convection in samples of aspect ratio Gamma = 0.23 and Gamma = 1/2 up to Rayleigh number Ra = 2 x 10(12) are prented. The broad range of Prandtl numbers 0.5 < Pr < 10 is considered. In contrast to some experiments, we do not e any increa in Nu/Ra(1/3) with increasing Ra, neither due to an increasing Pr, nor due to constant heat flux boundary conditions at the bottom plate instead of constant temperature boundary conditions. Even at the very high Ra, both the thermal and kinetic boundary la
