摘要
本文应用二阶全展开ETG有限元离散格式与大涡模拟相结合的方法对固定在槽道一侧的方形障碍物的绕流进行了数值模拟 ,计算了雷诺数为 40 0 0 0的湍流情况下的绕流流场 ,将模拟结果与实验结果及他人的数值结果进行了对比 ,符合较好 ,表明大涡模拟与所论的具有较高精度的数值算法相结合 。
Large eddy simulation cooperated with the second order full expension ETG finite element method is applied to simulate the flow over a square obstacle mounted on the floor of a channel. The flow field at Reynolds number of 40000 is simulated. The numerical results fit well with reported experimental and numerical results. It shows that LES cooperated with appropriate discrete scheme is good at identifying the large-scale vortices in the flow field and their time history.
