Formation of Positively Charged Liquid Helium Clusters in Supercritical Helium and their Solidification upon Compression.
Positively charged ions were produced in supercritical helium at temperatures from 6 to 10 K and up to 2 MPa using a corona discharge. Their mobility was measured via current-voltage curves, and the hydrodynamic radius was derived using Stokes law. An initial increase and subsequent decrease of hydrodynamic radius was observed and interpreted in terms of growth, compression and solidification o...

متن کاملInstability of Plane Couette Flow
The energy gradient theory has been proposed with the aim of better understanding the mechanism of flow transition from laminar flow to turbulent flow. In this theory, it is suggested that the transition to turbulence depends on the relative magnitudes of the energy gradient amplifying the disturbance and the viscous friction damping that disturbance. For a given flow geometry and fluid propert...

متن کاملOpen Channel Helium Flow during Rupture Event
Open channel fluid flow principles are applied to understand how helium might behave in the event of a release or spill in a long tunnel enclosure. An example would be helium flowing along the Tevatron accelerator tunnel as a result of some rupture of a header system. Buoyant forces would drive the helium along the ceiling until a vent to atmosphere is reached. An analogy is water flowing up to...
