摘要：
The simulation of hydraulic characteristics was carried out with Larger Eddy Simulation (LES) and Volume of Fluid (VOF) method. The numerical results show that the flow condition is smooth, the length of lateral cavity gradually increases with the size of lateral enlargement increases, the maximum pressure value on the lateral wall appears after the bottom cavity, the upper part of the lateral cavity region was longer than the lower part due to gravity and the backwater does not intrude into bottom cavity. The numerical results agree well with the experimental date. The new lateral aerator has good hydraulic characteristics and the LES with VOF method can well predict the hydraulic characteristics after the new lateral aerator.
