An unstructured grid technique has a good flexibility for a complex geometry, and already its usefulness has been demonstrated for full aircraft computations. In the three-dimensional, high-Reynolds number viscous flow, the very fine and stretched grids are required to resolve accuately thin boundary layers developed along the body surface. In this paper, RANS (Reynolds-Averaged Navier-Stokes) computations are carried out in transonic and high Reynolds number flows around an ONERA Model M5 configuration by using a Spalart-Allmaras one-equation turbulence model on a hybrid unstructured grid system. With respect to pressure distributions, CL-a, CL-CD and CM-CL curves, and boundary layer transition lines, the present computed results are quantitatively compared with other computed results and wind-tunnel testing data. Especially, the drag prediction is considerately improved by the flowing strategies: (1) High resolution of surface grids around each leading edge; (2) Extension of NUM (Normalized Unstructured Mesh) method; and (3) Modification of transition parameters such as C13 and C14 in the Spalart-Allmaras one-equation model.", "subitem_description_type": "Other"}]}, "item_5_description_32": {"attribute_name": "資料番号", "attribute_value_mlt": [{"subitem_description": "資料番号: AA0032819022", "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: NAL SP-53", "subitem_description_type": "Other"}]}, "item_5_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "航空宇宙技術研究所"}]}, "item_5_publisher_9": {"attribute_name": "出版者(英)", "attribute_value_mlt": [{"subitem_publisher": "National Aerospace Laboratory (NAL)"}]}, "item_5_source_id_21": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0289-260X", "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": "AN10097345", "subitem_source_identifier_type": "NCID"}]}, "item_5_text_20": {"attribute_name": "その他キーワード", "attribute_value_mlt": [{"subitem_text_value": "数値解析"}, {"subitem_text_value": "航空力学"}, {"subitem_text_value": "流体力学及び熱伝導"}]}, "item_5_text_35": {"attribute_name": "JAXAカテゴリ", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ: 航空宇宙技術研究所"}]}, "item_5_text_36": {"attribute_name": "JAXAカテゴリ2", "attribute_value_mlt": [{"subitem_text_value": "JAXAカテゴリ2: AP"}]}, "item_5_text_43": {"attribute_name": "DSpaceコレクション番号", "attribute_value_mlt": [{"subitem_text_value": "DSpaceコレクション番号: 7"}]}, "item_5_text_6": {"attribute_name": "著者所属", "attribute_value_mlt": [{"subitem_text_value": "防衛庁 技術研究本部"}, {"subitem_text_value": "防衛庁 技術研究本部"}, {"subitem_text_value": "三菱重工業"}, {"subitem_text_value": "三菱重工業"}, {"subitem_text_value": "菱友計算"}]}, "item_5_text_7": {"attribute_name": "著者所属(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Japan Defense Agency Technical Research and Development Institute"}, {"subitem_text_language": "en", "subitem_text_value": "Japan Defense Agency Technical Research and Development Institute"}, {"subitem_text_language": "en", "subitem_text_value": "Mitsubishi Heavy Industries Ltd."}, {"subitem_text_language": "en", "subitem_text_value": "Mitsubishi Heavy Industries Ltd."}, {"subitem_text_language": "en", "subitem_text_value": "Ryoyu Keisan Co.

内容記述 | The CASPER (Computational Aerodynamics System for Performance Evaluation and Research) was developed at TRDI-JDA (Technical Research and Development Institute of Japan Defense Agency) in 1998. An unstructured grid technique has a good flexibility for a complex geometry, and already its usefulness has been demonstrated for full aircraft computations. In the three-dimensional, high-Reynolds number viscous flow, the very fine and stretched grids are required to resolve accuately thin boundary layers developed along the body surface. In this paper, RANS (Reynolds-Averaged Navier-Stokes) computations are carried out in transonic and high Reynolds number flows around an ONERA Model M5 configuration by using a Spalart-Allmaras one-equation turbulence model on a hybrid unstructured grid system. With respect to pressure distributions, CL-a, CL-CD and CM-CL curves, and boundary layer transition lines, the present computed results are quantitatively compared with other computed results and wind-tunnel testing data. Especially, the drag prediction is considerately improved by the flowing strategies: (1) High resolution of surface grids around each leading edge; (2) Extension of NUM (Normalized Unstructured Mesh) method; and (3) Modification of transition parameters such as C13 and C14 in the Spalart-Allmaras one-equation model. | |||||
