WebThis effort investigates the accuracy of some flux-split algorithms in high-speed viscous flows. Three methods are examined: 1) MacCormack and Candler's (MC) scheme, 2) the van Leer (vL) scheme and 3) the method of Roe. The problems studied include the blunt body flow at Mach 16 and the flow past a 240 ...

WebMay 1, 2000 · We propose a way to construct robust numerical schemes for the computations of numerical solutions of one- and two-dimensional hyperbolic systems of balance laws. In order to reduce the computational cost, we selected the family of flux vector splitting schemes. WebWarming flux vector splitting approach and the NND scheme are given. The NND scheme based on improved Steger-Warming flux vector splitting is used for the solution of 1-D and shown that the numerical oscillation is restrained .The finite difference method has higher order of accuracy and better efficiency.

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. WebJul 1, 1993 · A new flux splitting scheme is proposed. The scheme is remarkably simple and yet its accuracy rivals, and in some cases surpasses, that of Roe's solver in the … reah sims 4
