Sentence examples for propagating dust from inspiring English sources

The present work describes two new experimental set-ups allowing direct observation of isobaric and freely propagating dust flames at two sufficiently different scales to test the influence of scale on dust flame phenomena.

In present paper, nonlinear propagating dust acoustic solitary waves (DASWs) in a cold magnetized dusty plasma containing negatively charged dust particles, electrons, high- and low-temperature nonthermal ions in the presence of an external static magnetic field are investigated.

In this paper, a theoretical investigation has been made of obliquely propagating dust acoustic solitary wave (DASW) structures in a cold magnetized dusty plasma consisting of a negatively charged dust fluid, electrons, and two different types of nonthermal ions.

The traditional defence against propagating coal dust explosions is the application of dry stone dust.

The direct numerical simulations solve the full system of two phase gas dynamic time-dependent equations with a detailed chemical kinetics for a plane flames propagating through a dust cloud.

The effect of radiation heat transfer in the case of coal dust flames propagating in layered particle-gas deposits cloud can result in the spread of combustion wave with velocity up to 1000 m/s and it is a plausible explanation of the origin of dust explosion in coal mines.

The final line of defence, however, is the use of barriers(du Plessis et al. 1995) to prevent a coal dust explosion from propagating.

The problems of lifting and dispersion of a dust layer behind a propagating shock wave must therefore be understood to ensure safety regarding secondary dust explosion hazards.

The problems of lifting and dispersing of a dust layer behind the propagating shock wave as well as ignition, combustion of coal particles and dust-layered detonation formation in a tube are numerically investigated.

The main purpose of applying active barrier systems in mines is to suppress methane explosions, prevent methane explosions escalating into coal dust explosions and to suppress coal dust explosions and prevent the explosions from propagating.
