Even if the collision frequency is much lower than characteristic ones of the turbulence, it is indispensable to realizing a steady state of perturbed distribution function delta f. In a low-collisionality limit, the low-order velocity-space moments of delta f as well as the ion heat transport flux agree with those in the quasisteady state of the collisionless turbulence. A spectral analysis of delta f in the velocity-space clarifies the transfer and dissipation processes of the entropy variable associated with fluctuations, where the phase mixing, the E   B nonlinearity, and the finite collisionality are taken into account.  A power-law scaling predicted by the theoretical analysis is also verified by the simulations in a subrange of the power spectrum which is free from the entropy production and the collisional dissipation.","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-785"}]},"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":[{}]}]},"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-785.pdf","filesize":[{"value":"480.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NIFS-785.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/10402/files/NIFS-785.pdf"},"version_id":"86832112-410c-4c54-9195-deba313eea69"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"gyrokinetics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"transport","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computer simulation","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":"Kinetic Simulation of Steady States of Ion Temperature Gradient Driven Turbulence with Weak Collisionality","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Kinetic Simulation of Steady States of Ion Temperature Gradient Driven Turbulence with Weak Collisionality","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":"10402","relation_version_is_last":true,"title":["Kinetic Simulation of Steady States of Ion Temperature Gradient Driven Turbulence with Weak Collisionality"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T20:42:48.080064+00:00"}
