This phenomenon is known as the ground effect or surface effect. WIG (Wind in ground effect) is a vehicle cruising near the sea to utilize this effect and to improve the efficiency of flight. In this report,　features of WIG is discussed and looking back the history of its developmentat first. Then the numerical simulation is carried out to estimate the ground effect on the vehicle. We changes the control parameters such as attack angle,distance from the sea surface and the speed (Reynolds number) to see their effect on the L/D (ratio of lift to drag) assuming that the sea surface is flat. Next, we change the shape of the sea surface due to the wave and investigate its effect on the flow field and L/D.","subitem_description_type":"Other"}]},"item_10002_description_5":{"attribute_name":"抄録","attribute_value_mlt":[{"subitem_description":"　翼と地面の距離が小さくなると揚力が増加し、誘導抵抗が減少するという現象が起きる。この現象を地面効果とよび、地面効果を積極的に利用する乗り物を地面効果翼機（WIG）または表面効果翼機という。日本では過去に試作機が作られたことが何度かあるが、まだ実用化されていない。しかし、WIGは高速水上輸送手段として、特に離島間の人や物資の輸送が高速化できるため、今後需要が見込まれる。本報告では、はじめにWIG の特長や開発の歴史を振り返る。次に効率のよいWIG を設計するためには、WIGまわりの流れを解析する必要があり、そのため流れの数値シミュレーションを行う。揚抗比に着目し、WIG の翼と地面との距離や翼の迎角を変化させ揚抗比に及ばす影響を調べる。実際のWIG は水面上を飛行することが想定されるため、波がWIG に及ぼす影響も調べる。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.32125/00000116","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"滋賀文教短期大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00011900","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0912-6759","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"河村, 哲也"},{"creatorName":"カワムラ, テツヤ","creatorNameLang":"ja-Kana"},{"creatorName":"Kawamura, Tetsuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"54","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000412241930","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000412241930"},{"nameIdentifier":"40143383","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40143383"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-05-01"}],"displaytype":"detail","filename":"紀要第25号_河村哲也.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Bvol.25_p(85)-(96)","url":"https://s-bunkyo.repo.nii.ac.jp/record/128/files/紀要第25号_河村哲也.pdf"},"version_id":"0a7485c7-36d0-4a83-a191-88df89d94bc5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"地面効果翼","subitem_subject_scheme":"Other"},{"subitem_subject":"高速海上輸送","subitem_subject_scheme":"Other"},{"subitem_subject":"数値シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"揚抗比","subitem_subject_scheme":"Other"},{"subitem_subject":"Wing-In-Grand-Effect","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fast sea transportation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Numerical simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"lift-to-drag ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"地面効果翼機周りの流れの解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地面効果翼機周りの流れの解析"},{"subitem_title":"Analysis of the Flow around the Wing-in-Ground Effect Craft","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["18"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-05-01"},"publish_date":"2023-05-01","publish_status":"0","recid":"128","relation_version_is_last":true,"title":["地面効果翼機周りの流れの解析"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2023-05-15T13:54:43.461634+00:00"}
