摘要
以CFD软件FLUENT为计算平台并进行二次开发,利用UDF模块及动网格技术建立数值水池,对二维矩形剖面及三维SUBOFF潜艇模型的水下自由横摇运动进行数值模拟。采用一种边界滑移动网格技术,保证网格不会发生畸变与重生的前提下,对物体的流场控制方程及刚体运动方程进行同步的耦合求解,计算其横摇周期和横摇阻尼等参数。
The CFD software FLUENT is applied to build the numerical tank, using secondary development platform with UDF module to make simulation of free rolling of 2D rectangle section and 3D SUBOFF under water. Besides,the technology of dynamic mesh slipping at boundary is used to make sure the grid won＇t distort or regenerate. The coupled equations governing the fluid and rigid-body motion are solved simultaneously,so as to get the period and damping of the rolling.
