AbstractLarge vapor cloud explosions (VCEs) and deflagration to detonation transition (DDT) events are of considerable interest to the petroleum refining and chemical processing industries. A detonation results in a very high flame speed and can significantly increase explosion energy and decrease standoff distance, increasing the blast load. Potential

Fluidic Jet Augmentation of a Deflagrated Turbulent Flame for Deflagration-to-Detonation
54th AIAA Aerospace Sciences Meeting, 2016Turbulence generation and induction within a deflagrated flame has been identified as a key mechanism for flame acceleration to detonation. The current state-of-the-art technique to achieve this mechanism is through the use of solid obstacles. These obstacles obstruct the flow and induce turbulent combustion with the goal of achieving detonation ...

Plasma deflagration and the properties of a coaxial plasma deflagration gun
Nuclear Fusion, 1970The concept of plasma deflagration is investigated theoretically and experimentally. Deflagration is a heating process which adds energy to a flowing stream under expansion. The equations governing the process are the same as the detonation "snowplough" process; therefore, deflagration is nothing more than the second solution of the set of conservation

The Acceleration of Fast Deflagration Waves
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1983AbstractIn an earlier paper Stewart and Ludford gave a theory of steady deflagration waves based on an ignition‐temperature model obtained from Arrhenius kinetics. They were able to describe analytically the structure of deflagration waves for the entire range of wave speeds between zero and the maximum (Chapman‐Jouget) value.

Deflagration of Emulsion Explosive
Advanced Materials Research, 2014Analog emulsion explosives production, observed its detonation. Deflagration and detonation of explosives determine how the phenomenon is long plagued with explosive materials in the field of military issues directly related to the safe and efficient use of explosives, by observing the special emulsion explosive blasting product, you can visually ...

Simulation Modelling of the Deflagration Behaviour
2010Mitigation through ignition and venting prevents potential detonation situations, but the resulting deflagration burn can still pose a threat to containment structures. The purpose of this research is to understand the general behaviour of vented deflagration using simulation.

Deflagration to detonation transitions and strong deflagrations in alkane and alkene air mixtures
Combustion and Flame, 1989Abstract Deflagration to detonation transitions and strong deflagrations for a large range of stoichiometric alkane (CH 4 , C 2 H 6 , C 3 H 8 , C 4 H 10 ) and air mixtures and alkene (C 2 H 4 , C 3 H 6 , C 4 H 8 ) and air mixtures have been studied systematically by varying surface roughness via the introduction of Shchelkin spirals.

Process Safety Progress, 2000
Abstract Two basic phenomenological models for deflagration propagation in dust clouds are discussed as the basis for interpreting explosion suppression results. The first model is based on oxygen diffusion to fuel dust particles as the controlling step in explosion propagation through a dust cloud.

Combustion, Deflagration and Detonation
2022The theory of combustion, deflagration and detonation is introduced together with the effect of pressure and density on the burning rate. In order to understand the basic concepts of detonation a simplified qualitative version of the detonation process is described.

The deflagration of hydrazine diperchlorate
Combustion and Flame, 1967Abstract Experimental studies encompassing the following aspects of the self-deflagration of the solid oxidizer hydrazine diperchlorate have been carried out: deflagration rate as a function of pressure and the effects of catalysts; flame demperature and temperature profile through the combustion wave; thermal decomposition and quenching of the ...
