本文建立一數值模式用以解析波浪通過不透水雙列潛堤流場。文中採用有限體積法和高度函數法配合雙方程 紊流模式求解雷諾平均Navier-Stokes方程式 (Reynolds Averaged Navier-Stokes Equations) 及連續方程式。數值計算結果的精確度藉由盧(1999)的試驗資料、線性波層流邊界層速度剖面及孤立波的波高、水平、垂直流速來檢驗之。最後，本文變換不透水雙列潛堤間距及波浪條件參數，探討波浪通過系列潛堤的渦流生成與消散、渦流位置以及渦流強度，並藉著水粒子軌跡探討此流場的堤址掏刷效應。

The main purpose of this study is to develop a numerical model for solving Reynolds Averaged Navier-Stokes Equations and Continuity equations. The present paper investigates the vortex generation and dissipation caused by period progressive waves passing over a series of submerged breakwaters. The accuracy of the numerical model was verified through the analytical solutions and the experimental data. The mechanism of the vortex is simulated by the developed model for different wave conditions and combinations of submerged breakwaters.
