TEMPERATURE MEASUREMENTS FOR POWDERED SOLIDS IN REFLECTED SHOCK WAVES.
Abstract
Measurements have been made to determinne the temperature behind reflected shock waves from an aerodynamic shock in argon containing a sample of powdered material. Time-resolved temperatures were measured photoelectrically by the brightness-emissivity method which employs a short duration flash tube. The measured temperatures were consistent, and about 10% lower than the calculated temperature for pure argon, over a 9 eV range of atomic excitation energies, indicating that thermodynamic equilibrium has been achieved. Calculated and measured densities for the atoms of the powder indicate that approximately 40% of the sample was uniformly distributed behind the reflected shock wave. (Author)
