Effects of scale and geometry on hydrogen-air detonations
Abstract
Recent experiments have investigated the influence of scale and geometry on the ability of a fuel-air mixture to propagate or sustain a detonation, and on the probability that a deflagration will undergo a transition to detonation. The data show that many past concepts concerning detonations need to be revised. In particular, the occurrence of detonations may not be as unlikely as previously considered, especially in large-scale industrial environments. This paper reviews some of the important recent experimental research, and provides some qualitative ideas concerning the interpretation of the experiments and their implications for improving safety.
