Journal ArticleDOI
Combustion of nanoaluminum at elevated pressure and temperature behind reflected shock waves
TL;DR: In this article, experimental measurements on the combustion of nanoaluminum particles behind reflected shock waves in a shock tube were performed at elevated pressures (4-32 atm) and temperatures (1200-2100 K) in the oxidizers oxygen and carbon dioxide, with nitrogen also present.
Journal ArticleDOI
Evidence for the transition from the diffusion-limit in aluminum particle combustion
TL;DR: In this paper, the transition from gas-phase diffusion-limited combustion for aluminum particles began to occur at a particle size of 10μm at a pressure of 8.5μm, indicating that reactions are occurring at or near the particle surface rather than in a detached diffusion flame.
Journal ArticleDOI
Nonsteady burning phenomena of solid propellants - theory and experiments
TL;DR: In this paper, the non-steady burning of solid propellants was investigated both theoretically and experimentally, with attention to combustion instability, transient burning during motor ignition, and extinction by depressurization.
Journal ArticleDOI
A correlation for burn time of aluminum particles in the transition regime
TL;DR: In this article, a study of the combustion times for aluminum particles in the size range of 3-11-μm with oxygen, carbon dioxide, and water vapor oxidizers at high temperatures (>2400 K), high pressures (4-25 ǫ atm), and oxidizer composition (15-70% by volume in inert diluent) in a heterogeneous shock tube has generated a correlation valid in the transition regime.
Journal ArticleDOI
Emission spectroscopy of flame fronts in aluminum suspensions
TL;DR: In this article, the authors derived the temperature of condensed phase emitters in the flame using polychromatic fitting of the continuum spectra to Planck's law, and the radial distribution of the temperature profile of the continuous emitters was found via Abel deconvolution and recovered the double front structure of the Bunsen flame cone.
