Explosive combustion of a gas mixture in radial annular chambers

Experimental results are described for continuous explosive ignition of compressed gases in flat annular chambers. The basis of the process is B. V. Voitsekhovskii's transverse-detonation method. Two types of tests were done: 1. The fuel components were fed through the cylindrical walls at the outer radius and the combustion products flowed out through the free surface at the inner radius. 2. The radial flow was reversed and the products flowed out with no wall at the outer radius. In both cases conditions were found where transverse detonation-like waves rotated around the annulus.
