摘要
采用FLUENT软件对斜坡堤越浪进行数值模拟,可以通过改变多孔介质区中的惯性阻力系数来模拟护面块体消浪作用的大小,但不同护面块体对应的惯性阻力系数不同,如何具体确定惯性阻力系数的值是数值模拟计算斜坡堤越浪量的难点所在。基于FLUENT软件平台并结合斜坡堤越浪的物模试验,综合考虑多种影响因素,运用多元回归方法,给出了扭王字块体的惯性阻力系数的计算公式;在此基础上,对比越浪量的数模计算值与物模试验值,二者吻合良好,表明文中构建的数值方法合理有效,可以较为准确地计算扭王字块体护面斜坡堤越浪量,为FLUENT软件数值模拟计算扭王字块体护面斜坡堤越浪量的研究开辟了一条新途径。
In the numerical study on mean overtopping rate of sloping breakwater based on FLUENT,the wave dissipation effect of armor blocks can be simulated by changing the inertia resistance coefficient in porous media,and how to get the inertia resistance coefficient in porous medium area reasonably and effectivelyt is a difficulty.Based on FLUENT software platform and combined with physical model test of sloping breakwater overtopping.Comprehensive consideration of various factors,this paper presents a formula for calculating the inertia resistance coefficient of accropode armor blocks by means of multiple regression method.The comparison and analysis with the physical model test results show that the numerical model constructed in this paper can reasonably and effectively simulate and calculate the mean overtopping rate of the sloping breakwater with accropode armor blocks.The research results open up a new way to study mean overtopping rate of the sloping breakwater with accropode armor blocks using FLUENT software.
