To improve these disadvantages, we have added hydrogen to a methane/air mixture, because the hydrogen has a very large reaction rate and high burning velocity. In this study, we have focused on a tubular flame which is formed in a stretched, rotating flow field. With this flame, effects of hydrogen addition on lean combustion have been investigated. We have measured the flame diameter, temperature distribution, burning velocity, and extinction limit. Results show that, as the concentration of added hydrogen is increased, (1) the flame diameter monotonically increases, (2) the fuel concentration at the extinction linearly decreases, and effective equivalence ratio decreases, and (3) burning velocity increases. These may be explained by the fact that the heat release rate determined in front of the preheat zone increases with the hydrogen addition. Although the details of the mechanism are unclear, the present results provide the first, basic idea on the practically important lean combustion.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/9318"}]}, "item_10_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本機械学会", "subitem_publisher_language": "ja"}]}, "item_10_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110002397016", "subitem_relation_type_select": "URI"}}]}, "item_10_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである。", "subitem_rights_language": "ja"}, {"subitem_rights": "日本機械学会", "subitem_rights_language": "ja"}]}, "item_10_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0387-5016", "subitem_source_identifier_type": "PISSN"}]}, "item_10_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_1615787544753": {"attribute_name": "出版タイプ", "attribute_value_mlt": [{"subitem_version_resource": "http://purl.org/coar/version/c_970fb48d4fbd8a85", "subitem_version_type": "VoR"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "山本, 和弘", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "21487", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "YAMAMOTO, Kazuhiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "21488", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "丸山, 昌幸", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "21489", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "MARUYAMA, Masayuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "21490", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "小沼, 義昭", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "21491", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "ONUMA, Yoshiaki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "21492", "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": "2018-02-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "JsMecEngB_64-622-1919.pdf", "filesize": [{"value": "566.2 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 566200.0, "url": {"label": "JsMecEngB_64-622-1919.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/7615/files/JsMecEngB_64-622-1919.pdf"}, "version_id": "8575b6fe-a843-4c77-93ec-d487ab183375"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Premixed Combustion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Burning Velocity", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Extinction", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Swirling Flow", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Lean Combustion", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hydrogen Addition", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Tubular Flame", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "希薄燃焼に及ぼす水素添加の効果", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "希薄燃焼に及ぼす水素添加の効果", "subitem_title_language": "ja"}]}, "item_type_id": "10", "owner": "1", "path": ["322"], "permalink_uri": "http://hdl.handle.net/2237/9318", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2008-01-18"}, "publish_date": "2008-01-18", "publish_status": "0", "recid": "7615", "relation": {}, "relation_version_is_last": true, "title": ["希薄燃焼に及ぼす水素添加の効果"], "weko_shared_id": -1}
