摘要
通过建立解析解、进行数值模拟和物理实验,研究了波浪水槽中非线性浅水波浪传播特性,给出了数值模拟中对应造波板做正弦运动的二阶入射边界条件。数值模拟采用高阶Boussinesq方程。实验结果、数值结果和解析解进行对比,并讨论了解析解的适用范围、高次谐波的产生及三波相互作用问题。
the propagation characteristics ot long non-hnear shallow-water waves in the wave flume are stuched by analytical solution, numerical simulation and physical experiment. The second order incident boundary condition of the fixed incident boundary is given, based on the sinusoicloo motion of the wave maker paddle. Higher order Boussinesq equations are used in numerical simulations. The application range of the analytical solution, the generation of higher harmonic and the triad interaction are discussed through the comparisons of experimental results, numerical results and analytical results.
