摘要：Hyperbolic conservation laws and convection dominated problems play an important role arise in applications as diverse as compressible and incompressible flows, aerodynamics, aero-acoustics, MHD and electromagnetism among many others. This is why devising robust, accurate and efficient methods for numerically solving these problems is of considerable importance and as expected, has attracted the interest of many researchers and practitioners. The need for such methods prompted and sustained the remarkable development of the so-called high-resolution finite difference, finite volume and finite element methods for non-linear hyperbolic systems. Essentially non-oscillatory (ENO), weighted ENO (WENO) methods and Runge-Kutta discontinuous Galerkin (RKDG) methods play a very important role in such developments. In this presentation, we will give a survey of WENO and RKDG methods.
