An improved quadrature rule for the flux-computation in staggered central
difference schemes in multidimensions
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 and improves the accuracy
for smooth solutions.
