摘　　要：利用引入VOF方法的RNGk-ε双方程紊流模型,对在台阶首部设置掺气挑坎的台阶式溢洪道进行了全程的三维数值模拟。通过模拟,得出计算域的水面线、速度场和压强场等水力特性,并用物理模型实测值对数值计算结果进行验证,两者吻合较好。说明采用数值模拟的方法研究台阶式溢洪道,以此得到真实的水力特性是可行的。Direct with the k-εdouble-equation turbulence mode,which was introduced bythe method ofVOF,the 3Dnumerical simulation were conducted,and the curvilinear free surface,velocity and pressure distributions were obtained in this paper.The results were in good agreement with that of physical model tests.The successful simulation shown that the flow in the stepped spillway could be numerically calculated.
