摘要
Abstract
To address the numerical generation of regular and random waves under complex marine conditions,a three-dimensional numerical wave tank model is established based on the Navier-Stokes equations and the VOF method for free-surface capturing,and a momentum-source wave-making method together with a damping wave-absorbing method is developed.For regular waves,the wave-making momentum source term is derived from finite-depth gravity wave theory.For random waves,the momentum source term is constructed using the JONSWAP spectrum,the equal-energy discretization method,and the linear superposition principle.The numerical stability of the proposed model is verified through grid and time-step independence analyses.The results show that,for regular waves,the numerically simulated wave profiles agree well with the third-order Stokes theory,and the frequency error is less than 4%.For random waves,the numerical wave spectrum is generally consistent with the target JONSWAP spectrum,and the deviation of significant wave height is less than 5%.The proposed method can accurately simulate the numerical generation and propagation of regular and random waves,and can provide a useful reference for wave simulations under complex marine conditions.关键词
