It is shown that the outlet flow has strong three-dimensionality with large lateral leakage from both sides of the valve plate, which results in that the outlet flow has the characteristics of a discontinuous separated flow rather than that of a jet flow. Empirical equations for pressure drop coefficient and moment coefficient around the plate axis are obtained, as well as a simple approximate method for estimating fluid force acting on the plate. The influence of an obstructing wall near the valve exit upon valve performances is also determined.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{"name":"クロカワ, ジュンイチ"}]}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Society of Mechanical Engineers"}]},"item_2_relation_44":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://ci.nii.ac.jp/naid/110002358598/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002358598/","subitem_relation_type_select":"URI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA0058509X","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00213764","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Associate Professor, Faculty of Engineering, Yokohama National University,  (156 Tokiwadai , Hodogaya-ku , Yokohama)"},{"subitem_text_value":"Engineer, Torei Co.
