| Summary |
Pure and Applied Cryogenics, Volume 6: Liquid Helium Technology focuses on the principles, techniques, methodologies, and approaches involved in liquid helium technology. The selection examines liquid helium technology at the National Bureau of Standards, properties of liquid helium, heat transfer to liquid helium, and noise associated with heat transfer to liquid helium II. Discussions focus on apparatus and instrumentation, test procedure, liquid helium as a cryogenic liquid, zero viscosity, momentum of heat flow, rotation and vortex lines, oscillation of vortex lines, and quantized |
