High Resolution of Unsteady Shock Waves around Compression Corners Using Unstructured Adaptive Meshes

摘要

Numerical simulation, which can be used to examine flow fields quantitatively and in detail, has become very important recently. However, a numerical method which agrees well with the experi- mental results has not yet been established. This is due to the lock of resolution in complicated flow patterns containing numerous shocks. In the present work, an adaptive refinement/coarsening algorithm is developed and applied to transient shocked flows over single and double wedges.
