Lee-Huang-Yang effects in the ultracold mixture of ^{23}Na and ^{87}Rb with attractive interspecies interactions

open access: yesPhysical Review Research, 2021
The beyond-mean-field Lee-Huang-Yang (LHY) correction is ubiquitous in dilute ultracold quantum gases. However, its effects are often elusive due to the typically much larger influence of the mean-field (MF) energy.

Thermodynamic and Economic Feasibility of Energy Recovery from Pressure Reduction Stations in Natural Gas Distribution Networks

open access: yesEnergies, 2020
A big amount of the pressure energy content in the natural gas distribution networks is wasted in throttling valves of pressure reduction stations (PRSs).

Multistage Expansion Co-Planning of Integrated Natural Gas and Electricity Distribution Systems

open access: yesEnergies, 2019
This paper focuses on expansion co-planning studies of natural gas and electricity distribution systems. The aim is to develop a mixed-integer linear programming (MILP) model for such problems to guarantee the finite convergence to optimality.

Experimental study on the influence of initial desorbed gas from crushed coal on the dynamic effects of coal and gas outburst

open access: yesMeitan xuebao
A large amount of gas rapidly released during coal and gas outburst is an important cause of dynamic effects such as outburst shock waves and coal-gas two-phase flow.

Techno-Economic Assessment of Turboexpander Application at Natural Gas Regulation Stations

open access: yesEnergies, 2019
During the natural gas pipeline transportation process, gas stream pressure is reduced at natural gas regulation stations (GRS). Natural gas pressure reduction is accompanied by energy dissipation which results in irreversible exergy losses in the gas ...

An analytical model for gas overpressure in slug-driven explosions : insights into Strombolian volcanic eruptions [PDF]

open access: yes, 2012
Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.

Expansion of a one-dimensional Bose gas: the role of interactions and kinetic-energy driving

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2022
Abstract We study the expansion of a one-dimensional boson gas by initialising it in a small region of a chain, and then suddenly allowing it to expand into the remainder of the chain. We consider three initial ground-state configurations: the Mott insulator, the conventional superfluid, whose momentum density is sharply peaked at zero ...

Deformation energy of tectonic coal and its role in coal and gas outbursts

open access: yesMeitan xuebao
Coal and gas outburst is an underground dynamic disaster driven by coal deformation energy and gas expansion energy. Although the comprehensive effect hypothesis of outbursts has been widely recognized, the role of coal deformation energy in outbursts ...

A Multi-Attribute Expansion Planning Model for Integrated Gas–Electricity System

open access: yesEnergies, 2018
Gas-fired power plants are environmentally friendly because of their high efficiency rates and low CO2 emissions. On the other hand, the output power of renewable generators is stochastic, meaning that additional capacity must be held in reserve ...
