Two examples of PIV data compared with corresponding CFD data, that is, leading edge separation vortices of a cranked arrow wing and a tip vortex of a rectangular wing, are presented in order to evaluate the capability of PIV as a CFD validation tool. As a result, the detailed velocity field data via PIV are proved to be useful in the evaluations of different turbulence models and algorithms in CFD analyses. Also, important issues to be carefully considered for getting successful results in the CFD validation using PIV are mentioned, such as differences in spatial/temporal resolutions and data point locations., 資料番号: AA0048469030, レポート番号: JAXA-SP-04-012}, pages = {178--183}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {PIV(粒子画像流速測定法)を用いたCFDコード検証について}, volume = {JAXA-SP-04-012}, year = {2005} }
