The results show that the side-gap leakage has dominant influence upon the fluid force characteristics, which can be well predicted by a small modification of the conventional two-dimensional potential flow theory. For the case of a large side gap, the pressure over the valve plate becomes nearly uniform and is equal to the upstream one. And that the fluid force is expressed as a function of only the velocity ratio of the jet to the upstream, if the side-gap-leakage is less than the mainflow volume. It is pointed out that the separation zone at the back of a valve plate is recovered very rapidly due to momentum transfer effects of side-gap-leakage, and that the outlet flow from a valve plate is not contracted with its width nearly equal to the valve opening one. The experimental formulae of moment coefficient are also presented.","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/110002358729/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002358729/","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, Yokohama National University, 156 Tokiwadai, Hodogaya, Yokohama, 240 Japan."},{"subitem_text_value":"Graduate Student, Yokohama National University."},{"subitem_text_value":"Engineer, Torei Co.
