有顶板开孔沉箱所受波浪力的数值分析

Numerical calculation on the wave forces acting on perforated caisson with top cover

利用流体体积(VOF)方法并结合k-ε模型以及等温状态下的气体状态方程数值计算规则波对有顶板开孔沉箱的作用,将数值计算结果与物理模型试验数据分别对总水平力、前开孔板和后实体板的压力分布以及顶板总力等物理量进行对比,验证了所建立的数学模型和数值计算方法的有效性和可靠性,为分析有顶板开孔沉箱的波浪力提供了有效的计算方法.

The VOF method, k-ε model and air state equation under a constant temperature condition are utilized to calculate the wave force of regular wave acting on a perforated caisson with a top cover. Through the comparison of various parameters such as the total horizontal forces, the pressure difference between the front face and the back face of the front plate, the pressure on the back wall and the top cover between the numerical results and test data, respectively, it is known that numerical results agree well with the test data. It may be concluded that the established method can be used to calculate the wave forces acting on the perforated caisson with the top cover.
