A new shock-tube facility for studying combustion phenomena in mixtures containing condensed species Conference Paper uri icon


  • Two shock tubes at The Aerospace Corporation have been refurbished for the study of fundamental processes related to the formation and reaction of solid and liquid aerosols at elevated temperatures. One shock tube is intended for the study of powdered aerosols and other condensed-phase species, while the second tube is designed for die study of gas-phase reactants. Recent upgrades and additions include a new high-vacuum system, an optimized velocity-detection scheme, a computer-based data acquisition system, and new techniques and procedures for handling experiments involving gas/powder mixtures. Diagnostic techniques include laser extinction for particle volume fraction and size, optical pyrometry for particle temperature, laser-light scattering for particle size and number density, temporally and spectrally resolved emission from gas-phase species, and a Scanning Mobility Particle Sizer. Details on the setup and operation of the shock tube and diagnostics for the study of heterogeneous combustion processes are given, and sample results are presented.
