Remarks on High-Resolution Non-Oscillatory Central Schemes
for Multi-Dimensional Systems of Conservation Laws. Part I: An Improved
Quadrature Rule for the Flux-Computation.
Knut-Andreas Lie and Sebastian Noelle
We present a new second-order, nonoscillatory, central difference scheme on
two-dimensional, staggered, Cartesian grids for systems of conservation
laws. The scheme uses a new, carefully designed integration rule for the
flux computations and thereby takes more propagation directions into
account. This effectively reduces grid orientation effects produced for
two-dimensional, radially symmetric gas flows.
