Temperature measurement in spherically conveying detonation waves. Experimental results with an 800 mm apparatus
Abstract
The gas temperature in spherically converging detonation waves in a stoichiometric propane-oxygen mixture in a hemisphere of inner diameter 800 mm was spectroscopically investigated. For the temperature measurement 5% Ar was added to the mixture and the intensity of Ar lines was determined as a function of time. The measured peak temperature behind the detonation front shows the same radial dependence on the radius as the pressure. The specific gas volume behind the detonation front within a radius of 40 mm, estimated from the measured temperatures and pressures, is always larger than that calculated from the Hugoniot equation at the same pressure.
