Abstract

The numerical simulation of wave slamming on a 3D platform deck was investigated using a coupled Level-Set and Volume-of-Fluid (CLSVOF) method for overset grid system incorporated into the Finite-Analytic Navier-Stokes (FANS) method. The predicted slamming impact forces were compared with the corresponding experimental data. The comparisons showed that the CLSVOF method is capable of accurately predicting the slamming impact and capturing the violent free surface flow including wave slamming, wave inundation and wave recession. Moreover, the capability of the present CLSVOF method for overset grid system is a prominent feature to handle the prediction of wave slamming on offshore structure.

基于水平集-流体体积法的超置网格系统三维海洋平台甲板波浪撞击数值模拟

将超置网格系统的水平集和流体体积(CLSVOF)耦合方法与有限解析Navier-Stokes (FANS)方法相结合，对三维平台甲板上的波浪撞击进行了数值模拟。将预测的撞击冲击力与相应的实验数据进行了比较。对比结果表明，CLSVOF方法能够准确地预测撞击冲击，并能捕捉到撞击波、淹没波和退去波等猛烈的自由表面流动。此外，该方法对超调网格系统的处理能力是处理海上结构物冲击预报的一个突出特点。
