Direct initiation of detonation in a hydrogen-oxygen mixture diluted with nitrogen

The direct initiation of plane and cylindrical detonation waves in a hydrogen-oxygen mixture diluted with nitrogen using an exploding copper wire and a moving piston is investigated.Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhidkosti i Gaza, No.6, pp. 151–156, November–December, 1992.The authors are grateful to G. D. Smekhov for calculating the Chapman-Jouguet detonation parameters and to V. V. Mitrofanov, who reviewed the article, for his useful comments.
