Flux vector splitting of the inviscid gasdynamic equations with application to finite-difference methods. Steger, J., L. & Warming, R., F. Journal of Computational Physics, 40(2):263-293, Academic Press, 4, 1981.
Paper doi abstract bibtex The conservation-law form of the inviscid gasdynamic equations has the remarkable property that the nonlinear flux vectors are homogeneous functions of degree one. This property readily permits the splitting of flux vectors into subvectors by similarity transformations so that each subvector has associated with it a specified eigenvalue spectrum. As a consequence of flux vector splitting, new explicit and implicit dissipative finite-difference schemes are developed for first-order hyperbolic systems of equations. Appropriate one-sided spatial differences for each split flux vector are used throughout the computational field even if the flow is locally subsonic. The results of some preliminary numerical computations are included. © 1981.
