Experimental study and weighting analysis of factors influencing gas desorption

open access: yesFrontiers in Earth Science, 2023
Gas is one of the necessary contributing factors for coal and gas outburst accidents, and the gas desorbed in coal is the energy carrier in the outburst process.

THE DUST AND GAS CONTENT OF THE CRAB NEBULA [PDF]

open access: yesThe Astrophysical Journal, 2015
We have constructed MOCASSIN photoionization plus dust radiative transfer models for the Crab Nebula core-collapse supernova (CCSN) remnant, using either smooth or clumped mass distributions, in order to determine the chemical composition and masses of the nebular gas and dust.

Interacting galaxies on FIRE-2: the connection between enhanced star formation and interstellar gas content [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
We present a comprehensive suite of high-resolution (parsec-scale), idealised (non-cosmological) galaxy merger simulations (24 runs, stellar mass ratio ~2.5:1) to investigate the connection between interaction-induced star formation and the evolution of ...

Molecular gas content of shell galaxies [PDF]

open access: yesAstronomy & Astrophysics, 2019
Shells are fine stellar structures that are identified by their arc-like shapes around a galaxy. They are currently thought to be vestiges of galaxy interactions and/or mergers. The study of their number, geometry, stellar populations, and gas content can help us to derive the interaction or merger history of a galaxy.

RELIABILITY OF WATER CONTENT DATA FOR NATURAL GAS-HYDRATE SYSTEMS USING SEMI-EMPIRICAL CORRELATIONS [PDF]

open access: yes, 2023
Water in natural gas can result in various operational problems, which may lead to equipment failure and plant shutdown. Knowing the amount of water capable of condensing from natural gas is essential.

Gas Content of Graphites

open access: yesNature, 1960
ARTIFICIAL graphite for use in graphite-moderated nuclear reactors, as anodes for mercury vapour rectifiers, and crucibles for vacuum fusion work should contain little gas. Otherwise, when the graphite is heated to operating temperatures, the gas is desorbed, resulting in adverse effects. For example, in the graphite-moderated nuclear reactor, hydrogen

Experimental and Simulation Studies on Adsorption and Diffusion Characteristics of Coalbed Methane

open access: yesEnergies, 2019
Coalbed methane (CBM) content is generally estimated using the isotherm theory between pressure and adsorbed amounts of methane. It usually determines the maximum content of adsorbed methane or storage capacity.

Effect and mechanism of geological structures on coal seam gas occurrence in Changping minefield

open access: yesEnergy Science & Engineering, 2020
The main factor affecting the gas content in a coal seam is the geological structure, and different types of geological structure have different effects on the gas content in a coal seam.

Optimization and application of W-P model for regional prediction index of outburst coal seam

open access: yesMeikuang Anquan, 2021
In order to obtain the internal correlation of gas content and gas pressure suitable for different mining areas in Guizhou Province, and accurately calculate the measured values of the two indexes in line with the characteristics of coal seams, the W-P ...
