Cryogenic thermodynamics at ultra-high Reynolds and Rayleigh numbers.

Hydrodynamique cryogénique aux très hauts nombres de Reynolds et de Rayleigh.

Author(s) : CHABAUD B., HÉBRAL B., PIETROPINTO S., et al.

Summary

Turbulent flows are characterized by various figures relating to the nature of the intensification. Cryogenics makes it possible to achieve record levels: low-temperature helium has a kinematic viscosity 200 times lower than that of air. This viscosity may be modulated according to pressure; helium's critical point is easily accessible (5.2 K and 2.2 atm) and its thermodynamic properties are well-known in this region. These characteristics make it possible to achieve very high Reynolds and Rayleigh numbers and very broad parameter ranges.
