【摘要】：極端波浪環(huán)境作用下,浮體易發(fā)生上浪拍擊等強(qiáng)非線性現(xiàn)象,這一問題也是波浪與浮體相互作用研究的難點(diǎn)之一。該文基于高階CIP(Constrained Interpolation Profile)法,采用THINC(Tangent of Hyperbola for Interface Capturing)數(shù)值技術(shù)精確捕捉自由液面,建立了二維多相流強(qiáng)非線性數(shù)值水槽模型。通過模擬線性波和孤立波的生成、傳播過程,對(duì)該模型的收斂性、穩(wěn)定性及造波性能進(jìn)行了全面的驗(yàn)證與分析。利用該數(shù)值模型模擬和分析了極端波浪對(duì)浮體的強(qiáng)非線性作用。
[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.
