摘要
波浪的实时预测可应用于很多领域,该文基于线性理论建立了波浪预测方法,并推导了单点测量、多点测量和移动点测量条件下,可预报域的理论范围.在此基础之上,根据物理含义给出了可预报域的判别指标能量比m0,通过物理水槽试验验证了确定性波浪预报的效果,得出了不同波浪测量条件下,能量比m0阈值为0.01时,可预报域内计算波浪和实际波浪吻合较好.此外,还讨论了不同测量条件下,可预报域的影响因素.
Abstract
The real-time prediction of waves can be applied in many fields.In this paper,a wave prediction method is established based on linear theory and the range of the theoretical predictable domain is derived under single-point measurement,multi-point measurement,and moving-point measurement conditions.Based on this theory,a discriminant indicator,energy ratio m0,is provided based on physical interpretation to determine the predictable domain.The effectiveness of deterministic wave prediction is verified through physical wave tank experiments.An analysis is conducted on the different wave measurement conditions,indicating that when the energy ratio m0 threshold is set to 0.01,a good agreement is achieved between the calculated waves within the predictable domain and the actual waves.Additionally,the influencing factors of the predictable domain under different measurement conditions are discussed.
