摘要 以平板驱动二维腔剪切流作为标准算例,对比考察镜像虚粒子与静态虚粒子两种边界设置方法,分别在两种不可压缩流SPH(ISPH-DF与ISPH-DI)中的应用。结果显示,采用静态虚粒子边界,计算精度更高;ISPH-DF算法较ISPH-DI法更加稳定。 Two different wall boundary conditions treatments-mirror boundary conditions and static boundary conditions were implemented to simulate lid-driven cavity flow with incompressible SPH(ISPH) algorithm.The algorithms include density-invariant ISPH(ISPH-DI) and divergence-free ISPH(ISPH-DF).The results show that simulations are more accurate with the static particles boundary and the ISPH-DF algorithm are more stable then the ISPH-DI algorithm.
