利用高分辨率的实验系统研究了汞中的瑞利-贝纳德对流在其阈值附近的变化。流体的普朗特数在0.02和0.04之间变化。两个不同的固定对流制度，称为粘性和惯性的实验证据，报告。它们对普朗特数P的依赖性与小普朗特数极限下的理论预测进行了比较。
Rayleigh-Benard convection in mercury is studied in the vicinity of its threshold with a high-resolution experimental system. The Prandtl number of the fluid is varied between 0.02 and 0.04. The experimental evidence of two different stationary convective regimes, called viscous and inertial, is reported. Their dependence on the Prandtl number P is compared with the theoretical predictions in the small Prandtl-number limit.
