Waves in gas centrifuges: a review

open access: yesJournal of Physics: Conference Series, 2020
Abstract Waves in gas centrifuges are generated by scoops for withdrawal of the gas. The physics of the waves and their role in the gas dynamics are under discussion. Strong centrifugal and Coriolis forces have dramatic impact on the properties and dispersion relation of the waves.

Simulation of gas flow around the scoop in a two-dimensional (r-θ) centrifugal rotor using the direct Monte Carlo method [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2023
One of the driving factors for creating axial flow inside the gas centrifuge rotor to increase the separation performance is the scoop. Due to the exposure of the scoop to the high Mach gas flow, the flow will be shocked, and strong gradients will occur ...

Water-Gas Imbibition Relative Permeability: Literature Review, Direct versus Indirect Methods and Experimental Recommendations [PDF]

open access: yesE3S Web of Conferences, 2023
When an active aquifer encroaches into a gas bearing reservoir or when an oil rim sweeps gas during late depletion of the gas cap, gas displacement by liquid is important for estimating the gas recovery.

Mathematical Modeling of Non-Stationary Hydraulic Process Occurring in the Gas Centrifuge Cascade During the Separation of Multicomponent Isotope Mixtures [PDF]

open access: yes, 2016
This article presents results of development of the mathematical model of nonstationary separation processes occurring in gas centrifuge cascades for separation of multicomponent isotope mixtures. This model was used for the calculation parameters of gas

A fast method for trapped gas determination [PDF]

open access: yesE3S Web of Conferences, 2019
Gas reservoirs are mainly produced by depletion with an aquifer rise; reservoir simulation requires two main SCAL inputs: the amount of trapped gas by the aquifer (residual gas saturation: Sgr) and the relative permeability to water due to aquifer ...

Inverted bucket centrifugation with fluorinated oils and its applications to T2 cut-offs [PDF]

open access: yesE3S Web of Conferences, 2020
Hydrocarbon reservoirs with a large column height as well as tight gas rocks require a large range of capillary pressures to describe the saturation of fluids present in these formations. While mercury injection capillary pressure (MICP) can achieve high

Centrifuge modelling of gas pipelines undergoing freeze–thaw cycles [PDF]

open access: yes, 2021
Frost heave and thaw settlement are two critical factors that need to be considered in the design of chilled gas pipelines in cold regions. Due to the variation in seasonal temperature and operating conditions (e.g., pressure and temperature at the ...

Centrifugal Separation of Boron Isotopes Using Boron Trichloride as Processing Gas

open access: yesJournal of Isotopes, 2018
Stable isotopes had been widely used in the industrial production, health care, fundamental physics research, and so on. Natural boron has two stable isotopes: 10B (19.9%) and 11B(80.1%).

To “Keep the Genie Bottled Up”: U.S. Diplomacy, Nuclear Proliferation, and Gas Centrifuge Technology, 1962–1972 [PDF]

open access: yes, 2017
In the 1960s and early 1970s, U.S. policymakers maintained a complex effort to limit the dissemination of gas centrifuge technology for enriching uranium, which they saw as an inherent nuclear proliferation risk. Recognizing that controls could not stop
