| Popis: | Flow around JAXA HLD (High Lift Devices) wind tunnel model is analyzed by RANS (Reynolds Averaged Navier Stokes) CFD (Computational Fluid Dynamics) method and compared with the experimental data obtained by JAXA. Unstructured mesh with overset technique is used for mesh generation around realistic configuration with small parts such as slat clip. It was shown that the slat clip made a difference in the flowfield especially around the edge of the slat. Baldwin-Barth and Spalart-Allmaras one equation models are used for turbulence model and the former gives better agreement with the experiment. 資料番号: AA0063742031 レポート番号: JAXA-SP-07-016 |
