Dynamic SGS (LDSGS)モデルを用いたLESによって解析した. 従来のDynamic Modelによる解析の多くはチャンネルなど比較的単純な流れを対象としていた. これらの解析では計算の不安定を掛するため, モデル係数をダイナミックに同定する過程において流れの一様な方向に平均化を施すことにより, 計算の安定化を図る例が多い. これに対して, LDSGSは流跡線に沿って平均化操作を施し, 計算の安定化を図る手法である. この手法は3次元物体周りのように一様な方向の存在しない流れ場にDynamicタイプのSGSモデルを適用する際に有効である. 本研究では2次元角柱周りの乱流渦放出流れに対してLDSGSによる安定化手法を用いたDynamic Smagorinsky Modelを適用し, 計算安定性, 精度の両面から同手法の有効性を確認した.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"特集
