摘要

The present paper deals with the robust and accurate multi-dimensional limiting processrnfor higher-order discontinuous Galerkin (DG) and correction procedure via reconstructionrn(CPR) methods on triangular and tetrahedral meshes. MLP, which has been originally developedrnin finite volume method (FVM), provides an accurate, robust and efficient oscillation-control mechanismrnin multiple dimensions for linear approximation. This limiting philosophy can be hierarchicallyrnextended into higher-order Pn approximation. The resulting algorithm have been developedrnfor both DG and CPR methods mostly on two-dimensional triangular grids. This method can bernreadily extended three-dimensional space and efficiently implemented. Through extensive numericalrnanalyses and computations, it is demonstrated that the proposed limiting approach yields therndesired accuracy and outstanding performances in resolving compressible inviscid and viscous flowrnfeatures.
