The main calculation algorithm of the method is an extension of SIMPLE algorithm to present the governing equations based on curvilinear co-ordinates, maintaining the Cartesian velocity components as dependent variables. The standard k - epsilon turbulence model is used for closure of the Reynolds equation. This method is applied to calculation of turbulent flows in two-dimensional and axi-symmetrical dump diffusers with uniform and distorted inlet velocity profiles. The results are compared with the data obtained from the present experiments and the other available data. The general flow pattern and velocity distribution are successfully predicted and the results show good agreement with experimental data, especially when using the QUICKER scheme for the convection terms approximation. Pressure loss can also be predicted using the fine grid, but improvement must be achieved in the computational method to be able to predict pressure loss with moderate grid. The treatment of the pressure correction equation in general curvilinear coordinates employed in this work enhances the stability and robustness of calculation.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0007012","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 SP-7","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":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"石川島播磨重工業株式会社技術研究所"},{"subitem_text_value":"石川島播磨重工業株式会社技術研究所"},{"subitem_text_value":"石川島播磨重工業株式会社航空宇宙事業本部"},{"subitem_text_value":"石川島播磨重工業株式会社航空宇宙事業本部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Research Institute Ishikawajima-Harima Heavy Industries Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"Research Institute Ishikawajima-Harima Heavy Industries Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"R&D Dept., Aero-Engine and Space Operations Ishikawajima-Harima Heavy Industries Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"R&D Dept., Aero-Engine and Space Operations Ishikawajima-Harima Heavy Industries Co., Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"安藤, 安則"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"河合, 理文"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤, 幸徳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤, 秀実"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ando, Yasunori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawai, Masafumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sato, Yukinori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Toh, Hidemi","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":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0007012.pdf","filesize":[{"value":"967.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0007012.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43228/files/nalsp0007012.pdf"},"version_id":"772c4de9-fe8c-4c07-80c9-8bcfd5974b73"}]},"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":"ダンプ・ディフューザの乱流流れ場数値解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ダンプ・ディフューザの乱流流れ場数値解析"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43228","relation_version_is_last":true,"title":["ダンプ・ディフューザの乱流流れ場数値解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:19:49.264578+00:00"}
