摘要

Turbulent pipe flow of liquid He-4 has been investigated for Reynolds numbers from Re = 3 x 10(3) to Re = 3 x 10(6) to examine He I and He II turbulence in the presence of shear. The extremely low kinematic viscosity of liquid helium allows us to achieve high Reynolds numbers in small laboratory apparatus. Our results agree with those using classical fluids, showing the utility of helium as a fluid for turbulence research. (C) 2000 Published by Elsevier Science B.V. All rights reserved. [References: 3]
