【摘要】 在Radder和Kirby发展的波浪折射绕射缓坡方程抛物型模型基础上,对这种模型进行了改进,改进后的模型除可以考虑波浪传播过程中的底摩阻损耗、非线性作用外,加入了风能输入对波浪传播的影响。基于风能输入项的波浪模型数值计算结果表明,在纯风浪情况下的计算结果与传统的风浪计算方法结果一致,在波浪传播过程中由于风的作用,将导致波高比无风作用下计算的波高大。更多还原

【Abstract】 Based on a parabolic mild-slope equation for the combined refraction and diffraction of waves, the term of th input wind energy for the parabolic model is discussed. The wind energy factor for deep water and shallow water wave growth is derived. Verifications for the model show that the result under the condition of wind wave is in agreement with that of the experimental formula. When the wind energy input is added in the parabolic equation, the computed wave height will increase comparing with the result under the condition without wind.更多还原
