The fluid has a quadratic density-temperature relationship, and the maximum density occurring at T_m. Cooling is accomplished by abruptly lowing the sidewall temperature, and the mean temperature passes through T_m in the course of cool-down. A finite-volume method is employed to acquire numerical solutions to the full, time-dependent two-dimensional Navier-Stokes equations. In order to simulate the realistic situations under micro gravity, the Rayleigh number, Ra, encompasses the range 10^5 ≤ Ra ≤ 10^8. The effects of the density inversion on the cool-down are illuminated. Based on the structures of the aidewall boundary layer, three characteristic flow regimes are identified at early time. The qualitative early-time behavior is detemined by the density inversion factor. Evolutions of the global fields of flow and temperature of each flow regime are described. The analysis of time-dependent heat transfer characteristics reveals that the cool-down process is divided into several definite transient phases. The relevant time scales for the overall cool-down process are estimated. The specific effects of the Rayleigh number, density inversion factor, and the aspect ratio of the container on each evolutionary stage are elaborated.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0035249000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-6808","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10632072","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KWAK, Ho Sang","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KUWAHARA, Kunio","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-23"}],"displaytype":"detail","filename":"SA0035249.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0035249.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31435/files/SA0035249.pdf"},"version_id":"5e0ff326-8446-4e29-98d1-35756ee0080f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Transient Cooling of an Enclosed Fluid through Its Maximun-Density Temperature","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Transient Cooling of an Enclosed Fluid through Its Maximun-Density Temperature","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1903"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31435","relation_version_is_last":true,"title":["Transient Cooling of an Enclosed Fluid through Its Maximun-Density Temperature"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:59:52.542821+00:00"}
