The direct photographic method was employed to investigate the influence of fuel flow rate and nozzle diameter, d, on the flame morphology. Emphasis was placed on the determination of the flame length, L_f, over a wide range of the fuel flow rate. It became clear that (i) as the nozzle velocty is increased from zero, the flame burning under conditions of mixing with air is induced and its length is monotonically increased until a laminar-to-turbulent\ntransition occurs, and (ii) after the transition takes place, the turbulent flame length is substantially independent of further increase in fuel jet velocity. A few relationships pertinent to the flame\nlength, i.e. L_f versus u_j, L_f/d versus, Re, and L_f/d versus d, were proposed and examined. In the laminar diffusion flame case, effects of nozzle diameter and Reynolds number on the flame length\nappear if the experimental data are summarized using the dimensionless flame length, L_f/d. In contrast, a slight effect of the turbulent diffusion flame is observed. The hydrogen diffusion flames, for\nthe burner tube of 1.24mm i.d., are found to be perfectly stable at a nozzle velocity of 300m/s.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0451212X","subitem_source_identifier_type":"PISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040363","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"530","subitem_subject_scheme":"NDC"}]},"item_7_version_type_14":{"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":"TORII, Shuichi","creatorNameLang":"en"},{"creatorName":"鳥居, 修一","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"YANO, Toshiaki","creatorNameLang":"en"},{"creatorName":"矢野, 利明","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"IWASHITA, Masatatsu","creatorNameLang":"en"},{"creatorName":"岩下, 正竜","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"NISHINOHARA, Hideki","creatorNameLang":"en"},{"creatorName":"西ノ原, 英樹","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"AN00040363_v35_p7-12.pdf","filesize":[{"value":"929.9 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"AN00040363_v35_p7-12.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/10666/files/AN00040363_v35_p7-12.pdf"},"version_id":"c3ee1b1a-7583-416e-bbe1-cb18fa35e3c9"}]},"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":"An Experimental Study on Flame Characteristics of Hydrogen Diffusion Flames","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An Experimental Study on Flame Characteristics of Hydrogen Diffusion Flames","subitem_title_language":"en"},{"subitem_title":"水素拡散火炎の火炎特性に関する研究","subitem_title_language":"ja"}]},"item_type_id":"7","owner":"18","path":["36","5355"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-03-25"},"publish_date":"2012-03-25","publish_status":"0","recid":"10666","relation_version_is_last":true,"title":["An Experimental Study on Flame Characteristics of Hydrogen Diffusion Flames"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-20T05:02:54.063174+00:00"}
