Converging cylindrical detonations are produced using Perry-Kantrovitz-type apparatus. Equimolar oxyhydrogen and similar oxyacetylene mixtures are utilized both for test and igniting gases. Effects of many experimental parameters on the stability of converging cylindrical waves are examined. It is concluded that the effects of the corner, the partitioning diaphragm, the ingniting mixtures and the initial pressures and species of the test gas should be noted in obtaining stable and approximately cylindrical converging waves. Although the observed propagation velocity is not well reproduced, the acceleration of the converging wave is strongly recognized in approaching the center.
