Ignition and combustion of a single aluminum particle in hot gas flow
TL;DR: In this article, the initial and bright-spot diameters of the aluminum particle are measured directly from the images by using the in-house automated data processing routines, and the results suggest that with the goal of decreasing the total time, suitable methods can be employed for different conditions.
Journal ArticleDOI
Experimental investigation of the combustion products in an aluminised solid propellant
TL;DR: In this paper, a variety of experimental techniques ranging from quenching and dynamic measurement, to high-speed CCD video recording, were used to study aluminium combustion behaviour and the size distribution of the initial agglomerates.
Journal ArticleDOI
Effect of ambient temperature on the ignition and combustion process of single aluminium particles
TL;DR: In this paper, the effects of ambient temperature on the ignition and combustion process of single aluminium particles (40-170μm) were examined, and it was shown that the particle ignition probability is very sensitive to the ambient temperature.
Journal ArticleDOI
Characterization of heat release rate by OH* and CH* chemiluminescence
TL;DR: In this paper, a deep neural network model was developed to determine the distribution of heat release rate with OH* and CH* chemiluminescence, and the validation results showed that the model performed satisfactorily.
Journal ArticleDOI
Ignition and combustion characteristics and agglomerate evolution mechanism of aluminum in nAl/JP-10 nanofluid fuel
TL;DR: In this paper, the energy release properties of aluminum (Al) nanoparticles in droplets and the influence of oxygen content on agglomerate evolution were studied using a CO2 laser ignition system with online diagnosis, intermediate sampling and offline analysis.

Experimental study of stages in aluminum particle combustion in air
TL;DR: In this article, an experimental study of Al particle combustion in air is presented, in which uniform Al particles were formed and ignited in air using a pulsed micro-arc discharge using a three-wavelength pyrometer, partially burned particles were quenched and cross-sectioned.
Journal ArticleDOI
Dynamics of aluminum combustion
TL;DR: In this paper, a study has been performed modeling both steady and unsteady combustion of aluminum, including the effects of multiple oxidizers and their products, oxide accumulation on the surface of the burning aluminum particle, and convection.
A Summary of Aluminum Combustion
TL;DR: In this article, a two-dimensional unsteady state kinetic-diffusion-vaporization controlled numerical model for aluminum particle combustion is presented, which solves the conservation equations, while accounting for the species generation and destruction with a 15 reaction kinetic mechanism.
Journal ArticleDOI
On the mechanism of asymmetric aluminum particle combustion
TL;DR: In this article, the results of an experimental study of the combustion of single aluminum particles in N2/O2 and pure O2 gas mixtures were presented and interpreted, and the relationship between aluminum particle combustion behavior and particle internal and surface structure and composition was illustrated.
