    This work focuses on the study of hybrid mixtures explosions in a 36 L dust explosion apparatus including mixtures of methane/niacin, methane/cornstarch, ethane/niacin and ethylene/niacin in air. By utilizing basic characteristics of unitary dust or gas explosions, a new formula is proposed to improve the prediction of the LFL of the mixture.   A two-dimensional model of natural gas explosion characteristics for premixed combustible mixture was established. In the model, considering control action imposed on an explosion from turbulence and chemical reaction kinetics, a turbulent combustion model coupled with reduced mechanism of detailed chemical reaction kinetics was set up.

In this study, we investigated the explosion parameters of vapor-liquid two-phase JP (C10H16, tricycle [, 6] decane)/air mixtures, and reported new experimental data obtained at various.

Get this from a library. A study of explosions of gaseous mixtures. [Alonzo P Kratz; Crandall Zachariah Rosecrans]. Abstract. Spherical detonations have been initiated by solid explosive (Tetryl) charges in well-mixed stoicheiometric air mixtures with each of the hydrocarbons, ethane, propane, n-butane, isobutane and ethylene at atmospheric to initiation, the gases were contained in plastic bags; total gas volume and available path length were up to m 3 and 2 m.

ROSECRANS BULLETIN No. ENGINEERING EXPERIMENT STATION p OBUSunD By TiH UxIvanarrT or ILLINOIS, UBaNA Fa~ze: Filnrryar Cams tUHE Engineering Experiment Station was established by act of the Board of Trustees of the University of Illinois on Decem- ber 8.

Gas Dynamics of Explosions and Reactive Systems documents the proceedings of the 6th Colloquium held at the Royal Institute of Technology in Stockholm, Sweden, August The meeting was held under the auspices of the Royal Swedish Academy of Sciences and the International Academy of Edition: 1.

The aim of this study is to undertake an extensive investigation on the explosion phenomenon of hybrid mixtures to obtain insight into the driving mechanisms and the explosion features affecting 5/5(1). The book is divided into nine chapters. Chapter 1 is devoted to fundamental thermodynamic concepts.

Chemical kinetics are covered in Chapter 2. The general oxidation characteristics of fuels and explosions are covered in Chapter 3. Chapter 4 covers flame phenomena in premixed combustible gases. Detonation is covered inmore». The data book "Safety Characteristic Data" is published in two volumes.

In the first volume "Flammable Liquids and Gases" the safety characteristics of pure substances in mixture with air have been published. In Volume 2 "Explosion Regions of Gas Mixtures" the properties of gaseous fuel/inert gas/oxidiser mixtures are in the centre of interests.

A GENERAL discussion on different aspects of explosions in gaseous mixtures took place at a meeting of the Faraday Society held on June 14 at the. Gas Pressure and Rock Movement Upon detonation, along with the shock wave, the solid explosive is instantly converted to superheated gas that is trying to occupy a sp to 20, times its original solid volume, and exerting a pressure that can exceed million psi.

Without this gas pressure, the fractured rock would not move and would.

The study of gases is divided into four key branches: the study of gas mixtures, formation of gases, theory of gases and yield definition.

These 4 branches are extensively applied in the physical chemistry. The study of gas mixtures is usually regarded as a perfect scientific tool for the investigation of numerous aspects of chemical.

An experimental study on pressure evolution during closed vessel explosions of several gaseous fuel-air mixtures was performed, at various initial pressures within bar and ambient initial.

Description. Companion volumes, Dynamics of Explosions and Dynamics of Reactive Systems, present revised and edited versions papers given at the Tenth International Colloquium on the Dynamics of Explosions and Reactive Systems held in Berkeley, CA in August Dynamics of Explosions primarily concerns the interrelationship between the rate processes of energy deposition in a compressible medium and the concurrent nonsteady flow as it typically occurs in explosion phenomena.

The paper also shows and discusses explosion ranges of hydrogen and hydrogen-natural gas mixtures. Pressure and temperature dependencies of the explosion limits of. The contents are arranged into chapters on gaseous detonations, heterogeneous detonations, condensed explosives, explosions, and interactions.

A companion volume was published, titled Dynamics of Flames and Reactive Systems. Methane–coal dust explosions can damage coal mining equipment and the working environment by overpressure, particulate release, and gas emissions. In this study, we investigated the influence of fuel concentration and coal particle size on multiple explosion parameters for methane–coal particle mixtures within a L sphere.

In the particular case of wheat starch/pyrolysis gases mixtures, the most severe explosion is found at values of fraction of oxygen demand for the fuel gases of ~, which indicates that, at stoichiometric conditions, hybrid mixtures have the capacity of causing more severe explosions than gas-only mixtures.

A more accurate correlation to predict an LFL for a hybrid mixtures explosion is necessary for risk assessment. This work focuses on the study of hybrid mixtures explosions in a 36 L dust explosion apparatus including mixtures of methane/niacin, methane/cornstarch, ethane/niacin and ethylene/niacin in air.

To study the effects of turbulence on the typical explosion characteristics (the maximum explosion pressure p max, the explosion duration time τ e, the maximum rate of pressure rise (dp/dt) max and the deflagration index K G) of methane-air mixtures, experiments are conducted in a standard L explosion spherical vessel, the concentration of methane varies from tothe mixtures .In the first volume "Flammable Liquids and Gases” the safety characteristics of pure substances in mixture with air have been published.

In Volume 2 “Explosion Regions of Gas Mixtures” .In order to reduce the number of accidents due to explosions of flammable gases in the goaf of coalmines, the conditions for explosion of flammable gases and their explosion limits, affected to a considerable extent by CO 2, are the use of our experimental equipment suitable for the study of explosion of polybasic explosive gas mixtures, we investigated the .
