Abstract
This paper presents thermal conductivity data for liquid3He taken at saturated vapor pressure (s.v.p.), and also the critical Rayleigh number at which convection begins. The temperature in this experiment ranged from 1.3 K to 3.2 K. We compare the thermal conductivity results with those of earlier experimenters, and find they agree well. The convective onset measurements are the first reported for3He, and we find the critical Rayleigh number Rac = 1500 ± 105, which is similar to the experimental values reported for4He. References are provided for the thermodynamic properties necessary for calculating the Rayleigh number Ra at s.v.p.
