摘要
FPSO在其生命周期内遭受的上浪风险很大,严重的上浪可导致结构的损坏。本文建立了三维数值水池,对规则波下固定FPSO的甲板上浪进行了数值模拟。得到了甲板和甲板室上的冲击载荷和上浪水在甲板上的水位高度以及波浪沿船首爬升、变形、破碎的过程。水池采用动边界造波,自由面由VOF方法来捕捉,在水池后段的动量方程中添加了源项以消除后端壁面的波浪反射。
FPSO can suffer great danger from Green Water, and severe Green Water can cause structure damages. This paper presents a three-dimensional numerical wave tank, which has been developed, A fixed FPSO is placed in the regular wave to simulate the phenomena of Green Water. Impact loads, wave height on the deck, the course of wave running up the stem, wave deforming and wave breaking can be obtained. Dynamic boundary was used to make waves and free surface to be captured by VOF method. In the posterior segment of the tank, sources term is added into the momentum equation to eliminate the reflection of the end wall
