Using a 2D FFT technique, the waves are separated into two instability modes. One is the streamline-curvature instability and the other is the cross-flow instability as predicted theoretically. It is shown that the T-S wave type instability appears when the frequency of excited disturbance is high, while the cross-flow instability becomes dominant when the frequency is low., 資料番号: AA0047776008, レポート番号: JAXA-SP-04-002}, pages = {25--28}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {後退円柱における不安定波の数値シミュレーション}, volume = {JAXA-SP-04-002}, year = {2005} }
