The heating surface is one end of a copper cylinder with a diameter in 20mm, which is heated by an electric heater wound around it. Heat flux at the heating surface may be increased up to about 1.7×106W/m2. The system pressure was changed in the range from 0.01 MPa to 0.3 MPa and the subcooling in the range from 0℃ to 70℃. The experiments are performed under two conditions; (1) the heating surface is kept stationary in water and (2) the heating surface can be moved reciprocally between the vapor and the liquid at a period of 0.67 sec to 2 sec and cooled intermittently. Boiling curves are obtained for these two cases. From the observations, it is seen that, on the downward-facing heating surface, bubbles formed beneath the heating surface can easily coalesce and form a large blanket of vapor which prevents primary bubbles from separating on the heating surface. In such a case, the boiling curves obtained become discontinuous in the nucleate boiling region and, at low heat flux, they are shifted to the film boiling region. The burn-out heat fluxes are lower in comparison with that for an upward-facing, horizontal surface. The intermittent cooling due to the reciprocal motion of the heating surface and the pressures less than atmospheric pressure may reduce the value of burn-out heat fluxes.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学工学部研究報告, 19(32), pp.1-8; 1989","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"51889","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tokita, Yuji"}]},{"nameIdentifiers":[{"nameIdentifier":"51890","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawae, Nobuji"}]},{"nameIdentifiers":[{"nameIdentifier":"51891","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shigechi, Tohru"}]},{"nameIdentifiers":[{"nameIdentifier":"51892","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamada, Takashi"}]},{"nameIdentifiers":[{"nameIdentifier":"51893","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hokao, Nobuhiro"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学工学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178418","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02860902","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"18805574","subitem_source_identifier_type":"ISSN"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Faculty of Engineering, Nagasaki University"}]},"item_3_version_type_16":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"時田, 雄次"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川江, 信治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"茂地, 徹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山田, 岹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"外尾, 暢晧"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"kogaku19_32_01.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kogaku19_32_01.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/14298/files/kogaku19_32_01.pdf"},"version_id":"6effadd8-458a-4204-92df-c3db0ae23f80"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"下向き水平伝熱面の沸騰熱伝達の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"下向き水平伝熱面の沸騰熱伝達の研究"}]},"item_type_id":"3","owner":"2","path":["1200"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-10-19"},"publish_date":"2010-10-19","publish_status":"0","recid":"14298","relation_version_is_last":true,"title":["下向き水平伝熱面の沸騰熱伝達の研究"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T00:21:46.397475+00:00"}
