湍流热对流中雷诺数的普朗特数和瑞利数依赖性遵循Grossmann和Lohse的统一理论[J. Fluid Mech.407，27（2000）; Phys. Rev. Lett. 86，3316（2001）]，并与各种最近的实验结果进行比较。这种依赖关系Re（Ra，Pr）比简单的整体幂律更复杂。对于Pr=5.5和10（8）
The Prandtl and Rayleigh number dependences of the Reynolds number in turbulent thermal convection following from the unifying theory by Grossmann and Lohse [J. Fluid Mech. 407, 27 (2000); Phys. Rev. Lett. 86, 3316 (2001)] are presented and compared with various recent experimental findings. This dependence Re(Ra,Pr) is more complicated than a simple global power law. For Pr=5.5 and 10(8)
