A Photographic Investigation of Flame Movements in Gaseous Explosions. VII. The Phenomenon of Spin in Detonation

In Part VI of this series, the results of photographic investigations into the phenomenon of “ spin ” in gaseous detonations up to June 1931 were described, and it was stated that further experiments were in hand, particularly as regards the effects of strong electric and magnetic fields upon the phenomenon, because it had already become evident “ that the present theory of detonation in gaseous media needs revision.” Since that time we have been continuously investigating the matter, and have now reached a new view of it which will be set forth herein. Before this can be done, however, it is necessary briefly to review the position three years ago when Part VI was published.
