摘要
本文采用直接解N-S方程式和标准的K-ε紊流模型方程式的方法,对二维强迫水跃和淹没水跃进行了数值模拟计算;给出了水跃在不同时刻自由表面的形状、流速及紊流输运量的变化,并和文献[1]的二维激光测速仪的实测结果进行比较,计算结果能较好地与试验结果相吻合。
The Rexnolds averaged N-S equations and a conventional two-equation K-ε model are used to predict the mean flow and turbulence characteristics of hydraulic jumps, which include forced free hydraulic jump, forced submerged hydraulic jump and submerged jump. The numerical predictions are compared with experimental data in Reference 1. The present algorithm is adequate for predicting multiple valued surface profile, mean velocity and turbulence structure of hydraulic jumps.
