中文摘要:
      以摇板造波方式为例,推导了造波方程和消波方程,建立了造波板运动特性与波浪参数的对应关系。设计了垂向板造波模型和摇板造波模型,利用Fluent软件进行了波浪数值模拟,使用UDF控制造波板运动,在近壁面附加动量源消波,对比分析了两种造波方式的优劣。垂向板造波方式适用于小幅波,对动力源要求低;摇板造波方式适用于中幅波,波浪质量好。依据数值模拟数据,设计并研制了物理样机,开展了波高测量实验。基于数值模拟的造波机设计方法能够快速确定造波方式和关键技术参数,大大缩短了研制周期,降低了研制成本,对研制新型造波机具有重要的借鉴意义。
英文摘要:
      The rocker flap wave maker method is taken as an example to derive the wave maker equation and the wave absorber equation. Then, the wave parameters are linked to the movement characteristics of wave maker plate. The vertical plate wave maker model and rocker flap wave maker model are designed to achieve the numerical simulation with the Fluent software. In the simulation, the UDF is used to control the movement of wave maker plate and additional momentum source is used near the wall to absorb wave. The advantages and disadvantages of the two methods are anaylzied. The vertical plate wave maker method is suitable for small wave and has no special requirement for power source, while the rocker flap wave maker method is suitable for medium wave and the generated wave is better. According to the simulated data, the physical prototype is designed and manufactured, the wave height is measured in the experiments. The waver generator design method based on the numerical simulation can identify the wave maker type and key parameters quickly to shorten the design cycle and reduce the development costs, which has important reference significance in developing novel wave generator.
