Unstructured grid based high-order methods in CFD

Z.J. Wang

Most unstructured grid based methods are first or second-order accurate. Although these methods have demonstrated tremendous success in engineering design, many applications such as wave propagation problems and vortex dominated flows require higher accuracy. In this talk, several popular high-order methods (order of accuracy > 2) such as k-exact finite volume, discontinuous Galerkin, spectral volume and spectral difference methods will be presented. Sample computational examples will be shown to demonstrate their ability. The pros and cons of structured and unstructured grid methods will be identified.  The talk will conclude with several remaining challenges in the research on high-order methods.
