气压生波的数值模似

目前海岸工程实验室中几乎都采用推板或摇板式生波机产生实验研究所需要的波浪。对于波浪、潮流、泥沙模型而言，这种生波机有两个缺点：一是妨碍潮流、泥沙的运移，二是产生二次反射使波浪场失真。是向水面喷压气体的气压装置来产生波浪，用于波浪、潮流、泥沙模型，可以避免上述两个缺点。本文通过数值模拟，认为这种方法是可行的。

Numerical simulation of pneumatic wave making

The wave is almost generated by rolling or blade wave makers in most coastal engineering labs at the moment.These wave makers have two shortcomings: one is the hampering of the movement of current and sediment, and the other is the wave field distortion caused by secondary reflection.A pneumatic system fixed above the water to produce waves by air jet can avoid the above shortcomings. The numerical simulation of the waves generated by this system is described in this paper.
