Liquid—Vapor Equilibrium in the System Equilibrium Hydrogen—Helium
(The American Institute of Physics, 1964-10-15)
Liquid—vapor equilibrium‐phase compositions for the binary system 20.40° equilibrium hydrogen—helium have been determined for six isotherms in the range 20.40°—31.50°K and at pressures up to 500 psia. The vapor recirculation ...
Photoconductivity in Single‐Crystal Tellurium
(The American Institute of Physics, 1964-02)
Measurements of the steady‐state and transient photoconductive behavior in the extrinsic range are presented and interpreted in terms of a simple trapping model. The change of electrical conductivity due to steady irradiation ...
Quantum Statistics and Slow Neutron Scattering by Gases
(The American Institute of Physics, 1967-12-15)
A surprisingly simple expression in ``closed form'' for the cross section d2σ/dΩdϵ for the scattering of thermal neutrons (including polarized neutrons) from an ideal quantum gas is derived. This result extends the work ...
Helium–Hydrogen Liquid–Vapor Equilibrium to 100 atm
(The American Institute of Physics, 1968-09-01)
Liquid–vapor phase compositions are given for 11 isotherms of the system normal‐hydrogen–helium over the range 15.5° to 29.8°K at pressures to 1500 lb/in.2 In this range, the mixture critical curve is located, the freezing ...
Liquid—Vapor Equilibrium in the System Normal Hydrogen—Helium
(The American Institute of Physics, 1964-03-01)
Liquid—vapor equilibrium phase compositions for the binary system normal hydrogen—helium have been determined for 11 isotherms in the range 15.50°—32.50°K and at pressures up to 500 psia. The vapor recirculation method of ...
Instability of Three‐Layer Viscous Stratified Flow
(The American Institute of Physics, 1969-12)
Instability of plane Couette flow of three superposed layers of fluids of different viscosity between two horizontal planes is investigated. It is found that there are two modes of disturbance dominated, respectively, by ...
Stability of Two Superposed Elasticoviscous Liquids in Plane Couette Flow
(The American Institute of Physics, 1969-03)
It is found that the elasticity in the liquid cannot only destabilize the flow, but it can also stabilize the flow for certain values of depth ratio, viscosity ratio, and elasticity ratio. The stabilizing or destabilizing ...
