Comparative Analysis of Fire and Explosion Properties of Lycopodium Powder

open access: yesEnergies, 2023
Lycopodium (L.) clavatum powder, due to its uniform particle size distribution and low equilibrium moisture content, is often used as a reference material and a calibration benchmark for dust combustion and dust explosion studies.

Experimental Study on the Influence of Different Coal Species on Gas and Coal Dust Explosion

open access: yesMeikuang Anquan, 2020
To further explore the propagation law of gas coal dust explosion with different coal species involved, 3 kinds of representative coal dust were tested in a self-made semi-enclosed pipe, and the flame propagation speed, flame surface luminescence ...

Dust Explosion Risk Assessment for Dry Dust Collector Based on AHP-Fuzzy Comprehensive Evaluation

open access: yesProcesses, 2022
Dry dust collectors are a typical dust and gas coexistence space. Dust explosion risk assessments should be performed for effective prevention and control of dust explosion accidents.

The timing and location of dust formation in the remnant of SN 1987A [PDF]

open access: yes, 2014
The discovery with the {\it Herschel Space Observatory} of bright far infrared and submm emission from the ejecta of the core collapse supernova SN\,1987A has been interpreted as indicating the presence of some 0.4--0.7\,M$_\odot$ of dust.

DETERMINATION OF EXPLOSION CHARACTERISTICS OF SUGAR DUST CLOUDS

open access: yesTransactions of the VŠB: Technical University of Ostrava, Safety Engineering Series, 2018
A dust explosion occurs when an airborne combustible dust cloud encounters an effective ignition source. The resulting pressure and temperature increase can severely injure people and damage surrounding equipment and buildings, and therefore needs to be ...

Systematic Blueshift of Line Profiles in the Type IIn Supernova 2010jl: Evidence for Post-Shock Dust Formation? [PDF]

open access: yes, 2011
Type IIn SNe show spectral evidence for strong interaction between their blast wave and dense circumstellar material (CSM) around the progenitor star. SN2010jl was the brightest core-collapse SN in 2010, and it was a Type IIn explosion with strong CSM ...

Explosion Characteristics and variation of oxidized coal dust

open access: yesMeikuang Anquan, 2023
Oxidized coal is a coal body that has undergone the process of warming up and cooling down, and has been widely used in mine fire area start-up, stratified mining, and re-mining of residual coal, etc.

Micromechanical model of bovine Haversian bone predicts strain amplification through soft interfaces [PDF]

open access: yes, 2013
Context. Recent observations of brown dwarf spectroscopic variability in the infrared infer the presence of patchy cloud cover. Aims. This paper proposes a mechanism for producing inhomogeneous cloud coverage due to the depletion of cloud particles ...

Retracted: Effect of coal dust parameters on gas‐coal dust explosions in pipe networks

open access: yesEnergy Science & Engineering, 2022
To study the effects of particle size of coal dust and mass concentration of coal dust on gas‐coal dust explosions, we conducted sedimentary gas‐coal dust explosion experiments using a pipe network system that included multiple components and individual ...
