风浪场在时间和空间上的演化机制尚未完全了解。人们已经提出了各种理论方法来模拟风浪的产生。为了检验它们的有效性，必须在受控条件下进行详细而准确的实验。由于几乎不可能获得所需的控制参数，并在现场实验中积累详细的数据，因此需要进行实验室研究。广泛的以前无法获得的结果在我们的实验室积累的风浪的空间和时间变化的各种风强迫条件下，并使用不同的测量技术进行审查。风浪场的空间特性，确定使用立体视频成像。利用X热片对风浪上方的湍流气流进行了研究。研究了定常风强迫下的波浪场以及冲击载荷作用下的波浪场。从一个统一的观点出发，对风浪的各个方面进行了广泛的讨论。证明了菲利普斯提出的随机方法优于迈尔斯提出的风浪生成的确定性理论。风浪演变的空间和时间分析之间的本质区别进行了讨论，导致考试的适用性可能的方法风浪模拟。
The mechanisms governing the evolution of the wind-wave field in time and in space are not yet fully understood. Various theoretical approaches have been offered to model wind-wave generation. To examine their validity, detailed and accurate experiments under controlled conditions have to be carried out. Since it is next to impossible to get the required control of the governing parameters and to accumulate detailed data in field experiments, laboratory studies are needed. Extensive previously unavailable results on the spatial and temporal variation of wind waves accumulated in our laboratory under a variety of wind-forcing conditions and using diverse measuring techniques are reviewed. The spatial characteristics of the wind-wave field were determined using stereo video imaging. The turbulent airflow above wind waves was investigated using an X-hot film. The wave field under steady wind forcing as well as evolving from rest under impulsive loading was studied. An extensive discussion of the various aspects of wind waves is presented from a single consistent viewpoint. The advantages of the stochastic approach suggested by Phillips over the deterministic theory of wind-wave generation introduced by Miles are demonstrated. Essential differences between the spatial and the temporal analyses of wind waves’ evolution are discussed, leading to examination of the applicability of possible approaches to wind-wave modeling.
