【摘要】：极端波浪环境作用下,浮体易发生上浪拍击等强非线性现象,这一问题也是波浪与浮体相互作用研究的难点之一。该文基于高阶CIP(Constrained Interpolation Profile)法,采用THINC(Tangent of Hyperbola for Interface Capturing)数值技术精确捕捉自由液面,建立了二维多相流强非线性数值水槽模型。通过模拟线性波和孤立波的生成、传播过程,对该模型的收敛性、稳定性及造波性能进行了全面的验证与分析。利用该数值模型模拟和分析了极端波浪对浮体的强非线性作用。
[Abstract]:Under the extreme wave environment, the floating body is prone to strong nonlinear phenomena, such as wave flapping, which is also one of the difficulties in the study of the interaction between waves and floating bodies. Based on the high order CIP(Constrained Interpolation profile method and THINC(Tangent of Hyperbola for Interface Capturing) numerical technique to accurately capture the free liquid surface, a two-dimensional nonlinear numerical model of multiphase flow is established in this paper. By simulating the generation and propagation of linear and solitary waves, the convergence, stability and wave-making performance of the model are verified and analyzed. The strong nonlinear effects of extreme waves on floating bodies are simulated and analyzed by using this numerical model.
