Ω-Stable Limit Set Explosions [PDF]

Transactions of the American Mathematical Society, 1986
Certain diffeomorphisms of two-dimensional manifolds are considered. These diffeomorphisms have a finite hyperbolic limit set which contains a limit set cycle. The only nontransverse cycle connection in these cycles is a complete coincidence of one component of the unstable manifold of one periodic point with one component of the stable manifold of ...

Effects of ammonia substitution on explosion limits of methane [PDF]

, 2023
As a hydrogen-rich and carbon-free fuel, ammonia is regarded as a promising carrier and storage medium for clean energy. By mixing methane with ammonia, the emission of carbon dioxide is also significantly reduced, which is of great significance for ...

Steam Explosion Pretreatment for Improving Wheat Bran Extrusion Capacity

Foods, 2022
Extrusion improves the texture of wheat bran and enhances its product edibility, making it a promising processing method. However, the extrusion performance of wheat bran without any treatment is not satisfactory and limits the utilization of wheat bran ...

Limitation of Atmospheric Composition by Combustion–Explosion in Exoplanetary Atmospheres [PDF]

The Astrophysical Journal, 2018
Abstract This work presents theoretical studies that combine aspects of combustion and explosion theory with exoplanetary atmospheric science. Super-Earths could possess a large amount of molecular hydrogen depending on disk, planetary, and stellar properties.

Use of explosibility diagrams in potentially explosive atmospheres [PDF]

MATEC Web of Conferences, 2020
Although the first research in the field was carried out by Davy in 1816, the first discovery emerged in 1891 when Le Chatellier defined the law for determining the explosive limits.

Study on the explosion characteristics of alcohol vapor cloud-feed powder dust cloud mixture during the deep processing of waste mash

Case Studies in Thermal Engineering
The explosion limits (LEL&UEL), maximum explosion pressure (Pmax), and minimum ignition energy (MIE) of mixtures composed of four combustible feed dusts and inflammable alcohol vapor are investigated in a modified 20-L spherical explosion system and a ...

Safe Separation of the Low-Concentration and Oxygen-Bearing Coal Mine Methane by Vacuum Pressure Swing Adsorption

Adsorption Science & Technology, 2014
Pressure swing adsorption (PSA) is a suitable method to enrich the concentration of methane in coal mine methane (CMM) separation processes. However, traditional PSA processes for low-concentration CMM can easily increase the concentration of methane to ...

Experimental determination and simulation of explosion limits of benzene-inert gas-air mixtures

, 1995
In this work, the influences of inert diluents, N-2 and CO2, on the explosion limits of benzene-air mixtures were investigated at two different initial temperatures.
