Two-dimensional imaging of glyoxal (C2H2O2) in acetylene flames using laser-induced fluorescence
H2O2). Laser-induced fluorescence spectra from glyoxal vapor using the same excitation wavelength of 428 nm showed the same strongest lines as the signal from the flame. Glyoxal was visualized in two different mo...

Deshydratation de l'alun d'ammonium
The formation of the two kinds of partially dehydrated amorphous alum can be explained by the water vapour gradient which appears within the sample during dehydration and by existence of a critical water pressure

Deshydratation de l'alun d'ammonium
Dehydration of hydrated ammonium alum is a function of physical gaseous pressure. During dehydration, two kinds of partially dehydrated amorphous alum appears. These solids differ in texture and residual water...

Structure and Extinction of Non-Diluted Hydrogen-Air Diffusion Flames
In this paper we study the structure of non-diluted hydrogen-air diffusion flames using both a starting kinetic mechanism and a reduced two-step mechanism with atomic hydrogen as an intermediate non-steady sta...

Reduced Kinetic Mechanisms for Premixed Hydrogen Flames
There have been a number of studies of structures and propagation velocities of premixed hydrogen-oxygen flames through numerical integrations of one-dimensional, adiabatic conservation equations. Especially n...

Reduced Kinetic Mechanisms for Acetylene Diffusion Flames
Previous studies of acetylene combustion have predominantly focussed on premixed flames, e.g. Frenklach and Warnatz [14.1] and Miller and Melius [14.2], while little attention has been given to non-premixed combu...

Reduced Kinetic Mechanisms for Premixed Methane-Air Flames
Methane-air flames have served as the first example for the development of a strategy to systematically reduce kinetic mechanisms. Premixed methane-air flames were first considered in [5.1] and [5.2], methane-air...

Reduced Kinetic Mechanisms and NOx Formation in Diffusion Flames of CH4/C2H6 Mixtures
Technical fuels very often consist of a mixture of several components with different physical and chemical properties. Since reduced mechanisms are typically derived for one-component fuels, the question arise...

Reduced Kinetic Mechanisms for Premixed Propane-Air Flames
Because of its low price, propane is often used as a reference fuel for hydrocarbon combustion. The combustion of most of the complex hydrocarbon fuels proceeds through a rapid decomposition to small C1–C3 hydroc...
