| 摘 要： | 基于线性波理论,采用VOF法、RNG k-ε的湍流模型,通过FLUENT软件平台的二次开发功能实现了质量源造波。利用多孔介质模型,在动量方程里添加多孔介质源项,对斜坡堤上铺设异型块体时的爬高与越浪进行了数值模拟,并通过模拟爬高值率定出FLUENT中多孔阻力系数与多种异形块体糙渗系数之间的关系,进而建立了可供实际应用的海堤上波浪爬高与越浪数值模型。

| Abstract: | Based on CFD software FLUENT and linear wave theory,and using VOF method and RNG turbulence k-epsilon mode,source wave-generating method is accomplished through UDF.Based on this wave-generating method,and using porous media mode,wave runup and overtopping are simulated while the sea dikes are paved with armor blocks.Moreover,the relationship between porous resistance coefficient and roughness coefficient of armor blocks is given. |

| Keywords: | FLUENT wave-generating porous media wave runup overtopping seawalls |
