建立了一个数学模型，分析了共振条件下印度奥里萨邦帕拉迪普港的长波振荡，以避免任何极端的波浪灾害。采用角点贡献边界元法求解部分反射边界条件下的亥姆霍兹方程。此外，还对边界均匀离散和非均匀离散的边界元格式进行了收敛性分析。数值格式也验证了解析近似和现有的研究基础上的港口共振。然后，放大因子估计在六个关键记录站在帕拉迪普港与多方向入射波和共振模式也估计在港口的边界。对不同方向入射波在不同共振模式下的帕拉迪普港内海面波场进行了预报。此外，还确定了系泊船舶在不同共振模态和定向入射波作用下的装卸安全位置。
A mathematical model is constructed to analyze the long wave-induced oscillation in Paradip Port, Odisha, India under the resonance conditions to avert any extreme wave hazards. Boundary element method (BEM) with corner contribution is utilized to solve the Helmholtz equation under the partial reflection boundary conditions. Furthermore, convergence analysis is also performed for the boundary element scheme with uniform and non-uniform discretization of the boundary. The numerical scheme is also validated with analytic approximation and existing studies based on harbor resonance. Then, the amplification factor is estimated at six key record stations in the Paradip Port with multidirectional incident waves and resonance modes are also estimated at the boundary of the port. Ocean surface wave field is predicted in the interior of Paradip Port for the different directional incident wave at various resonance modes. Moreover, the safe locations in the port have been identified for loading and unloading of moored ship with different resonance modes and directional incident waves.
