Flux Limited Dissipation Schemes for High Speed Unsteady Flows

摘要

Within the framework of the Local Extremum Diminishing (LED) or Essentially Local Extremum Diminishing (ELED) principle, efficient approaches to obtian a class of non-oscillatory high resolution schemes are presented. The LED principle requires that local maxima should not increase and local minima should not decrease to produce a monotonicity preserving scheme for scalar hyperbolic conservation laws.
