B}, month = {}, note = {A propagation of detonation wave shows particularly interesting phenomena, since the detonation wave is constituted from a three-dimensional shock wave system accompanied with a reaction front. Thus, the passage of a detonation wave draws cellular patterns on a soot-covered plate. Pressure and temperature behind the detonation wave are extremely high and have a potential to cause serious damages around it. Therefore, it is necessary from safety engineering point of view to quench the detonation wave with short distance from the origin. In this study, experiments applied high-speed schlieren photography are conducted to investigate behaviors of the detonation wave diffracting from two pieces of slits. The detonation wave produced in a stoichiometric mixture of hydrogen and oxygen is propagated through the slits and behaviors behind slit-plate are experimentally investigated. As a result, when the detonation wave diffracted from the slits, a shock wave is decoupled with a reaction front. Since two shock waves progagated from the slits interact each other at centre behind the plate, the detonation wave is re-initiated by generating a hot-spot enough to cause local explosion. It is also clarified that the shock wave reflected from a tube-wall induces detonation re-initiation., rights: 社団法人日本機械学会 rights: 本文データは学協会の許諾に基づきCiNiiから複製したものである relation: IsVersionOf: http://ci.nii.ac.jp/naid/110006453745/, text, application/pdf}, pages = {2354--2361}, title = {スリット板背後におけるデトネーション波の再開始過程 : デトネーション波の再開始と消炎過程の可視化(熱工学, 内燃機関, 動力など)}, volume = {73}, year = {2007}, yomi = {オバラ, テツロウ and オオヤギ, シゲハル} }
