摘要
为解决流体力学计算中部分区域作复杂相对运动以及固体空间接触等问题,介绍重叠网格法的计算原理,基于SC/Tetra软件,利用八叉树方法对含有2块各自绕轴旋转的板的交叉旋转模型进行网格划分,计算得到其流场的矢量流速分布,结果表明由于网格过渡得很好,旋转区域的形状对计算结果影响很小,旋转区域与周围区域的变量能得到很好的过渡.SC/Tetra软件具有完善的重叠网格计算功能,能有效解决相对运动问题,且操作简单、计算结果准确.
To solve the hydrodynamics calculation issues such as complex relative motion among regions, solid contact, and so on, the calculation principles of the overset mesh method is introduced, a crossrotation model with two plates which rotate around the axes of themselves is meshed by Octree method based on SC/Tetra software, and the velocity vector distribution of its flow field is calculated. The result indicates that, due to the good transition of mesh, the shape of rotation region has little effect on calculation results and the variables has good transition from the rotation regions to the surrounding regions. SC/Tetra has perfect overset mesh calculation function and can solve relative motion issues effectively with simple operation and accurate calculation results.
