Short Abstract: Fraunhofer Institut f¸r Chemische Technologie (ICT) has been active in the field of gas explosions during the last 25 years. Quite a lot of experiments predominantly on a medium and on a large scale have been performed - some of which with fundamental importance for the understanding of gas explosions. The intention of this paper is to present a review of selected results of our investigations achieved under the management of the late Dr Pf–rtner: detonation and deflagration of premixed fuel/air mixtures of different gases; the influence of turbulence, obstacles, cloud shape, ignition mode and ignition location on flame speeds and overpressures; combustion of flash evaporated, non-premixed fuel/air mixtures; and conditions for deflagration to detonation transition. We think that the presentation is especially attractive because we intend to use film material recorded during the tests for measuring the propagation of flames and of detonation fronts. Thus the topic will probably be better understood - apart from the fact, that the pictures are very impressive.
