However, wall distance is ambiguous in all but the simplest topologies. Besides, it is not at all evident that it bears a relationship to the structure of turbulence. Thus it is desirable to base modeling practice on wall proximity indicators which are local (pointwise) in nature and convey the influence of walls indirectly, based on parameters that 'measure' this proximity. Examples are the turbulence Reynolds number, k(exp 2)/(nu x epsilon), and various dot products of gradients such as (delta tau/delta x(sub j))(delta k/delta x(sub j)) where tau = k/epsilon, the turbulence time scale. Adhering to this modeling practice retains full generality of the model, since the entire formulation is local. Thus wall-distance-free models are tensorially invariant and frame-indifferent, applicable to arbitrary topologies and moving boundaries. They are also usable in conjunction with solvers based on either unstructured or structured book-keeping, executed on any computer architecture, including massively parallel processors. This paper illustrates the pointwise approach to turbulence modeling by introducing several such models of both linear and nonlinear types, and by demonstrating their performance in 2D and 3D flow eases.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063609008","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-06-029E","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Metacomp Technologies Inc."}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Metacomp Technologies Inc."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Goldberg, U.","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"476831","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":"2020-02-10"}],"displaytype":"detail","filename":"63609008.pdf","filesize":[{"value":"3.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"63609008.pdf","url":"https://jaxa.repo.nii.ac.jp/record/5739/files/63609008.pdf"},"version_id":"e1768caf-83a8-4147-a96d-79bca2fa21e4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"超音速機","subitem_subject_scheme":"Other"},{"subitem_subject":"航空機設計","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"計算流体力学","subitem_subject_scheme":"Other"},{"subitem_subject":"粘性抗力","subitem_subject_scheme":"Other"},{"subitem_subject":"レイノルズ数","subitem_subject_scheme":"Other"},{"subitem_subject":"乱流","subitem_subject_scheme":"Other"},{"subitem_subject":"遷移流","subitem_subject_scheme":"Other"},{"subitem_subject":"ナビエ・ストークス方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"表面摩擦","subitem_subject_scheme":"Other"},{"subitem_subject":"supersonic aircraft","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aircraft design","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulence model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"computational fluid dynamics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"viscous drag","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Reynolds number","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"turbulent flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"transition flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Navier-Stokes equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"skin friction","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Pointwise turbulence modeling for engineering applications","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pointwise turbulence modeling for engineering applications","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1005","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"5739","relation_version_is_last":true,"title":["Pointwise turbulence modeling for engineering applications"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:34:34.707722+00:00"}
