An adaptive version of immersed boundary method for simulating flows with complex stationary and moving boundaries is presented.The method employs a ghost-cell methodology which allows for a sharp representation of the immersed boundary.To simplify the implementation of the methodology,a volume-of-fluid method is introduced to identify the immersed boundary.In addition,the domain is spatially discretized using a tree-based discretization which is relatively simple to implement a fully flexible adaptive refi... 相似文献

分离流问题的研究在当前流体力学中占有十分重要的地位。它不仅具有重要的理论意义并且具有广泛的应用价值。本文着重评述三维分离流中的基本物理特性和它的流动结构。重点讨论了三维定常分离的两种模式及其判别准则;在三维分离流中应用奇点拓扑理论的定性分析;按照流动的物理特性对三维分离的分类;分离面的物理特性。最后简单介绍了目前在研究湍流边界层分离方面的进展。 相似文献
