The compressibility and the nonzero baroclinic vector are shown to violate the conservation of the enstrophy for the 2-D MHD transverse configuration and for the 2-D fluid motion. After the nonlinear saturation of the linearly fastest growing vortices, the vortices continue to coalesce until no more vortex pairing is allowed, owing to a finite length of the simulation system. The plasma inside the vortex is rarefied strongly by the fast magnetosonic rarefaction and each vortex is associated with an eddy current, which is inertia current in nature. The plasma flow velocity is enhanced at the periphery of the vortex and the net momentum transport and shear relaxation by the instability occur as long as the vortex pairing continues. Anomalous viscosity by the K–H instability increases with the vortex pairing and its increase is due to the growth of subharmonic modes. © 1997 American Institute of Physics.","subitem_description_type":"Abstract"}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics"}]},"item_2_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1063/1.872419","subitem_relation_type_select":"DOI"}}]},"item_2_relation_26":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1063/1.872419","subitem_relation_type_select":"URI"}}]},"item_2_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 1997 American Institute of Physics"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10987555","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1070664X","subitem_source_identifier_type":"ISSN"}]},"item_2_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"450","subitem_subject_scheme":"NDC"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Earth and Planetary Physics, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Miura, Akira"}],"nameIdentifiers":[{"nameIdentifier":"154726","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":"2019-03-28"}],"displaytype":"detail","filename":"PP_04_08_2871.pdf","filesize":[{"value":"311.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PP_04_08_2871.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/51715/files/PP_04_08_2871.pdf"},"version_id":"e45ccc03-29f3-4c3f-9219-302818b16b5c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"plasma magnetohydrodynamics","subitem_subject_scheme":"Other"},{"subitem_subject":"HELMHOLTZ INSTABILITY","subitem_subject_scheme":"Other"},{"subitem_subject":"MAGNETOHYDRODYNAMICS","subitem_subject_scheme":"Other"},{"subitem_subject":"TWO-DIMENSIONAL CALCULATIONS","subitem_subject_scheme":"Other"},{"subitem_subject":"COMPRESSION","subitem_subject_scheme":"Other"},{"subitem_subject":"CONVECTION","subitem_subject_scheme":"Other"},{"subitem_subject":"VISCOSITY","subitem_subject_scheme":"Other"},{"subitem_subject":"VORTICES","subitem_subject_scheme":"Other"},{"subitem_subject":"PLASMA INSTABILITY","subitem_subject_scheme":"Other"},{"subitem_subject":"PLASMA SIMULATION","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Compressible magnetohydrodynamic Kelvin–Helmholtz instability with vortex pairing in the two-dimensional transverse configuration","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Compressible magnetohydrodynamic Kelvin–Helmholtz instability with vortex pairing in the two-dimensional transverse configuration"}]},"item_type_id":"2","owner":"1","path":["11","122"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-01-06"},"publish_date":"2017-01-06","publish_status":"0","recid":"51715","relation_version_is_last":true,"title":["Compressible magnetohydrodynamic Kelvin–Helmholtz instability with vortex pairing in the two-dimensional transverse configuration"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:27:21.465913+00:00"}
