The effect of dissociation on shock wave propagation in air is evaluated by utilizing an effective isentropic index. The effect of dissociation is remarkable in the velocity profiles behind shock front for initial shock strengths between M(sub 0) = 4 and 8. Various mesh sizes on numerical computation are tested to determine the trajectory of the shock front in the time-space domain. In the case of perfect gases without dissociation, the 51 points on a constant time line are enough to integrate the characteristic equations. For dissociating gases, the 201 points are necessary to continue stable computations. Pressure profiles at a long time elapse after explosion reveal that the pressure in the vicinity of the explosion center gradually decreases below the initial pressure of the atmosphere different from similarity solutions.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063999000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RM-07-017E","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1121","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11983593","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"青山学院大学"},{"subitem_text_value":"首都大学東京"},{"subitem_text_value":"青山学院大学"},{"subitem_text_value":"宇宙航空研究開発機構 総合技術研究本部　計算科学研究グループ"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aoyama Gakuin University"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Metropolitan University"},{"subitem_text_language":"en","subitem_text_value":"Aoyama Gakuin University"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Computational Science Research Group, Institute of Aerospace Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"東野, 文雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"坂口, 堯"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"林, 光一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小川, 哲"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Higashino, Fumio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakaguchi, Gyo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hayashi, A.
