Turbulent and accelerating dust flames
Symposium (International) on Combustion, 1985Industrial dust explosions kill and severely injure workers as well as destroy property. While the hazards of gaseous explosions are well recognized, the same degree of care has not been exercised with regard to combustible dust. The agricultural industry has been especially plagued by this problem.

Investigation of Flame Regimes for Flame Acceleration to Detonation
2018 Joint Propulsion Conference, 2018Expanding hydrogen-air flames are studied in a semi-confined duct with an optical access test section. The focus of the work is to characterize the regimes of flame development in a highly turbulent environment and observe the Deflagration-to-Detonation (DDT) phenomenon.

Adding a certain percentage of hydrogen into the natural gas pipeline network is regarded as an efficient way to store and transport hydrogen. CH4-H2 binary fuel is also considered to be an important means of hydrogen utilization.

Flame morphology and self-acceleration of syngas spherically expanding flames
International Journal of Hydrogen Energy, 2018Abstract The self-acceleration of spherically expanding flames were investigated using a constant volume combustion chamber for CO/H2/O2/N2 mixtures over a wide range of initial pressure from 0.2 to 0.6 MPa, CO/H2 ratio from 50/50 to 10/90 and equivalence ratio from 0.4 to 1.5.

New Acceleration Techniques at INFN with FLAME
AIP Conference Proceedings, 2010INFN, in the frame of the Strategic Project PLASMONX, is developing New Acceleration Techniques based on Laser Produced Plasmas. The activity is carried out jointly with CNR and a few Italian Universities. The first results obtained in a collaborating small‐scale laboratory (ILIL‐CNR) aim to optimize the physical conditions and related diagnostics for ...

Model of accelerating coal dust flames
Combustion and Flame, 1985Abstract A model describing turbulent coal dust flame propagation and accelaration is based on the transient, macroscopic equations of change. The turbulent flame velocity was obtained from a simple correlative technique combining turbulence and chemical effects. Predictions indicate that a deflegrating coal dust flame can accelerate to high velocity

Accelerating flames in tubes—an analysis
Proceedings of the Combustion Institute, 2007Abstract Flame acceleration in tubes is studied. A tube filled with flammable mixture is closed at one end and open to the atmosphere at its second end. When ignition takes place near the closed end, it is well-known from experiments that the flame may accelerate, oscillate and eventually reach considerable speeds.
