We designed a computer program known as \"type-A\" to reproduce exactly the features of the SUMMAC Method. A technique for extrapolation of flow velocity components out into vacant space and a method for determining free surface are also described here in detail. Four items were proposed to improve the numerical stability of the original method. We designed an improved version of the computer program -\"type-B\", to integrate these four items. Both computer programs were tested on the \"Impinging Jet\" example. Starting from accurate initial values, the behavior of time advancing solutions was compared and discussed here. The improved version \"type-B\" proved superior to \"type-A\", and the so-called Hirt's \"General Corrective Procedure\" used to ascertain its effectiveness. The relationship between the lattice interval δx and time increment δt  is also discussed here. A trial analysis for a viscous flow example was performed successfully.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR1439000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-1439","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所航空推進研究センター"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aircraft Propulsion Research Center, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 金吾"}],"nameIdentifiers":[{"nameIdentifier":"474713","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TAKAHASHI, Kingo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"474714","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr0001439.pdf","filesize":[{"value":"559.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr0001439.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45423/files/naltr0001439.pdf"},"version_id":"b8e513aa-ac63-4f7e-b8f9-2b72f5049eee"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"SUMMAC method, free surface, impinging jet","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"SUMMAC法に関する考察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"SUMMAC法に関する考察"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45423","relation_version_is_last":true,"title":["SUMMAC法に関する考察"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:39:46.413327+00:00"}
