英文
cellular pier-
In this thesis a numerical model to solve the planear 2 - d depth - integrated flow ( dif ) has been established with irregular body - fitted mesh finite volume method and explicit maccormack predictor - corrector method and applied to the study of damming caused by a bridge pier under 14 working conditions varied with the combination of different pier shape. flow rate and contraction ratio
本論文採用非規則貼體網格有限體積法和顯式maccormack預測-校正法求解平面二維水深積分方程,對明渠水流運動的數值模擬方法進行了研究,並且應用該數值模型計算了14種不同的橋墩體型、來流、收縮比的組合工況下的橋墩壅水問題。The researching method is, firstly, to create a flow field model which is testified to be reliable on a large area, and to research the variations of discharge entering and out - flowing from hangzhou bay ; secondly, to simulate the discharge variation of main interest area near the bridge axis with a denser grid in a subarea of the coarse model
研究方法是首先建立大范圍的可靠適用的流場數值模型,研究進出杭州灣的流量變化;然後對感興趣的區域嵌套加密網格,利用橋墩物理模型測定的等效底摩阻系數,研究建橋前後在橋軸線上的流速、流量變化。
