Cryogenic He experiment on natural turbulent convection.
Number: pap. n. 071
Author(s) : KRALIK T., URBAN P., MUSILOVA V., et al.
Summary
Cryogenic helium gas is a suitable fluid for study of natural turbulent convection at very high Rayleigh numbers. We present an experimental method and a new result on Reynolds and Péclet numbers characterizing large scale circulation (LSC) of fluid at Rayleigh numbers within the range from 1011 to 1015. Observation of LSC is based on measurement of local temperature fluctuations of convecting helium. For experiments the authors used a specially designed cylindrical cell of height L = 0.3 m and diameter D = 0.3 m with minimized parasitic effects on studied convection, previously published on conf. CryoPrague 2006.
