We used a\nhigh-speed video camera and the Schlieren method to visualize the ignition phenomena. Experiments\nwere performed over a temperature range from 549 ± 10 to 1349 ± 11 K and a pressure range from\n56 ± 2 to 203 ± 13 kPa, and a non-diluted stoichiometric acetylene–oxygen mixture was chosen as the\ncombustible gas. We introduced a numerical simulation to help us understand the disturbed temperature\ndistribution behind bifurcated shock waves due to interference between reflected shock waves and the\nboundary layer developed behind incident shock waves. Additionally, we experimentally observed and\nevaluated quantitatively a tendency for ignition positions to be located farther from the reflecting wall\nas the temperature decreased behind reflected shock waves. To focus our attention on the ignition positions,\nwe classified the ignition types behind reflected shock waves as near-wall ignition and far-wall\nignition by 4.7 mm distance from reflecting wall. The criterion for these ignition types was estimated\nto be -1.0≦(∂ti/∂T5t)p5t≦-0.5. As a main object in this manuscript, we proposed an ignition model\nin which local ignition is induced at some distance from reflecting wall based on the numerical simulation\nand results; the local ignitions at a point distant from the reflecting wall are induced by the temperature\nrise, with the distance from the reflecting wall, immediately behind concave reflected shock waves\ndue to developing of bifurcated shock waves. We confirmed that there is no discrepancy between the proposed\nmodel and experimental results.","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/117847"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier Inc."}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.combustflame.2012.05.009","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2012 The Combustion Institute　\nNOTICE: this is the author’s version of a work that was accepted for publication in Combustion and flame.
