摘要
随着海上液化天然气的开采和卸载的发展,LNG船部分充满液舱的晃荡问题变得非常重要,成为一个重要的研究课题。文章采用VOF法对部分充满液舱的晃荡进行了数值模拟。结合动网格技术,针对二维矩形舱和三维立方体舱及薄膜型舱进行了计算。并将相关的横向力、波高和压力曲线与试验结果作对比,吻合较好。验证了此法的可行性和有效性。
With the development of offshore LNG production and offloading, sloshing of LNG in partially filled tanks has become an important research subject for the offshore industry.In this paper,VOF （volume of fluid） method is used for the numerical simulation of sloshing in partially filled liquid tanks. With the dynamic meshes,2D rectangular tank and 3D cubic tank and membrane tank are calculated. And the calculated results including transverse force and wave elevation and pressure curves, are compared with experimental results, well in agreement. The feasibility and validity of this method is validated.
