It is found from the simulation that the three-mode ITG system repeats growth and decay with a period which shows a logarithmic divergence for infinitesimal initial perturbations.  Accordingly, time average of the mode amplitude vanishes, as the initial amplitude approaches to zero. An exact solution is analytically given for a class of initial conditions.  An excellent agreement is confirmed between the analytical solution and numerical results.  The results obtained here provide a useful reference for basic benchmarking of theories and simulations of the ITG modes.","subitem_description_type":"Abstract"}]},"item_5_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-633X","subitem_source_identifier_type":"ISSN"}]},"item_5_text_8":{"attribute_name":"報告書番号","attribute_value_mlt":[{"subitem_text_value":"NIFS-619"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Watanabe,  T.-H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugama,  H.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sato,  T.","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":"2016-03-11"}],"displaytype":"detail","filename":"NIFS-619.pdf","filesize":[{"value":"583.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NIFS-619.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/10406/files/NIFS-619.pdf"},"version_id":"f810bfc2-351d-4d0c-8001-760939cd1b59"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Computer simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"drift waves","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"Non-dissipative Kinetic Simulation and Analytical Solution of Three-mode Equations of Ion Temperature Gradient Instability","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Non-dissipative Kinetic Simulation and Analytical Solution of Three-mode Equations of Ion Temperature Gradient Instability","subitem_title_language":"en"}]},"item_type_id":"5","owner":"3","path":["32"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-05"},"publish_date":"2010-02-05","publish_status":"0","recid":"10406","relation_version_is_last":true,"title":["Non-dissipative Kinetic Simulation and Analytical Solution of Three-mode Equations of Ion Temperature Gradient Instability"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:43:30.098370+00:00"}
