This paper describes an experimental study on the locations and shapes of pseudo-shock waves in straight rectangular ducts when the flows are choked at the duct exits. The experiment was done for Mach number at the duct entrance M∞ from 1.72 to 1.88 and for duct length L/D = 13.8~23.6, where L is the length of the duct and D (= 50mm) the width of the duct. It is shown that the locations of pseudo-shock waves move in a downstream direction with decreasing L/D and increasing M∞. As the locations of pseudo-shock waves move in a down-stream direction, the shapes of pseudo-shock waves change from λ -type to X-type. It is also shown that the location of the pseudo-shock wave in a duct can be predicted by the theory of the Fanno flow with normal shock wave when the flow is choked at the duct exit.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_77_publisher_11":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"室蘭工業大学","subitem_publisher_language":"ja"}]},"item_77_relation_15":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40003627626","subitem_relation_type_select":"NAID"}}]},"item_77_source_id_12":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05802415","subitem_source_identifier_type":"PISSN"}]},"item_77_source_id_14":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00238225","subitem_source_identifier_type":"NCID"}]},"item_77_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"423.84","subitem_subject_scheme":"NDC"}]},"item_77_version_type_21":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open
