摘要
采用LU-SGS隐格式离散N-S方程,求解过程引入超松弛系数。数值水槽试验研究发现,超松弛系数的引入可以提高计算结果收敛速度,其取值范围一般在1~1.3之间。应用LU-SGS算法,建立了高分辨率的大东港海域潮流泥沙数学模型,计算结果表明,该算法稳定性好,计算精度能够满足实际工程应用,具有模拟大范围海域潮流泥沙运动的能力。
LU-SGS implicit algorithm is applied in the discrete N-S equations to solve the calculation by the relaxation coefficient whose value range is 1~1.3 according to the numerical flume experiment. Based on LU-SGS implicit algorithm,2d tidal current and suspended sediment high resolution mathematical model in the Dadong Harbor is built with good verification which shows that the model can simulate the moving of tidal currents and suspended sediments.
