WebMay 20, 2000 · The conjecture is useful to the flux function development, for it indicates whether the flux scheme under consideration will be afflicted with these kinds of failings. Thus, a class of shock-stable schemes can be identified. ... An accurate and robust flux splitting scheme for shock and contact discontinuities. SIAM J. Sci. Comput., 18 (1997 ... WebFeb 17, 2012 · A flux splitting scheme (AUSMDV) has been constructed with an aim at removing numerical dissipation of the Van Leer-type flux vector splittings on a contact discontinuity. The obtained scheme is also recognized as an improved advection upstream splitting method (AUSM) by Liou and Steffen.
