Unstructured Adaptive Grid Refinement for Flow Feature Capture

摘要：

　　An unstructured grid adaptation technology has been developed for capturing flow features effectively.The face-based hierarchical data structure is used at grid refinement procedure.The difference of suitable flow properties between cell and its neighbors for flow features detection.The results of different simulation cases show the strengths of unstructured grid adaptation technology.The flow features such as shock wave and vortex are resolved better with grids refinement.The grid adaptation also improves the computational accuracy of aerodynamic characteristics and loads.
