内容記述 | 乘り物および地上構造物の空力設計におけるCFDの適用性を調べるため高速鉄道の空力的問題の数値シミュレーションを行った。最初の問題は開放区間における2つの列車のすれ違いで、相対運動する格子上で3次元非定常オイラー方程式を解き、実際の試験データと定性的に一致する結果を得た。第2の問題は列車の先頭がトンネルに突入する時の圧縮波の形成で、軸対称オイラー方程式に基づくシミュレーションは圧縮波形につき実用的な結果を与え、トンネル出口から放射される圧力波の強さを減らすための列車頭部の断面積分布の最適化を行うために利用された。 | |||||

内容記述 | Numerical simulation of aerodynamic problems in high speed railways has been performed to investigate applicability of Computational Fluid Dynamics (CFD) to aerodynamic design of vehicles and ground structures. The first problem treated here is passing-by of two trains in open area. Unsteady three dimensional Euler simulation using relatively moving grids has been conducted and the result qualitatively agrees with real testing data. The second problem is compression wave generation during train nose entry into the tunnel. Axisymmetric Euler simulation gives quite realistic results on the compression waveform and can be extensively used to optimize area distribution of the train nose for reduction of strength of the pressure wave radiated from the tunnel exit. | |||||
