The reliability of the simulations for both types of wings is investigated. The results obtained with different grid resolutions and different entropy fixes show that characteristics of the secondary vortex, which in turn influences the strength and position of the primary vortex, strongly depend on these parameters. Although the computed primary vortex on the delta wing disagrees with the experimental results on both strength and location, these discrepancies compensate each other and lead to good agreement with the experiments on the aerodynamic characteristics. On the other hand, the interactions of the two primary vortices on the double-delta wings are influenced by the strength and location of the vortices. More research is required for an accurate simulation of the leading-edge vortices over a double-delta wing., 資料番号: AA0032819019, レポート番号: NAL SP-53}, pages = {109--114}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {デルタ翼とダブルデルタ翼の流れの数値シミュレーションの信頼性について}, volume = {53}, year = {2002} }
