Liquid Helium - an overview | ScienceDirect Topics

If the temperature of liquid helium is cooled below the critical value of T λ = 2.1768 K (at saturated vapour pressure), the liquid becomes a quantum fluid called helium II. The most important property of helium II is superfluidity: mass flow without viscous friction. This phenomenon is similar to superconductivity (current flow without electrical resistance); both arise from the same

The two-fluid theory and second sound in liquid helium

The liquid below the transition was named helium II to distinguish it from the liq-uid above the transition, called helium I. Three properties dis-covered in the late 1930s were particularly puzzling. First, a test tube lowered partly into a bath of helium II will gradually fill by means of a thin film of liquid helium that flows without friction up the tube's outer wall. Second, in the

II. 0 Department of Physics and Astronomy Louisiana State University, Baton Rouge, Louisiana 70803 The excitation spectrum of liquid Helium II is re-examined using the formalism developed by Sunakawa et a!. In this formalism, certain divergent terms appear-a constant term and the terms involving products of two field operators. We show that it is necessary

Helium II Defined - Cryogenic Society of America

Helium II. This article, written by Dr. John Weisend, was originally published in the Spring 2010 issue of Cold Facts as part of his series, Defining Cryogenics.. Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium.

Heat Transport in Liquid Helium II | SpringerLink

The superfluidity of liquid helium II is equally unique physically. At present, the development of commercial uses which depend upon the unusual thermomechanical properties of liquid helium II is not as advanced. This is partially due to its inconveniently low temperature. Thus the greatest promise for commercially exploiting the properties of liquid helium II is in conjunction with systems

Helium is produced commercially and is commonly used in superconducting magnets in nuclear magnetic resonance (NMR) systems. At normal atmospheric pressure, liquid helium boils at at temperature of 4.2 Kelvin or -452.11 degrees Fahrenheit. It is important to have helium transfills scheduled in a timely manner to prevent the magnet from warming

Helium - TKK

Helium Helium is the second lightest element after hydrogen. It is known as a light gas that is used to float balloons. It becomes liquid when it is cooled to a very low temperature. Helium is the only substance that remains liquid at absolute zero of temperature, 0 K (zero Kelvin), or -273.15 Celsius. All other substances solidify at temperatures higher than 10 K, see a typical phase diagram
