WebFeb 1, 1994 · Then the ~'-moments of the above equation lead to split flux Euler equations ~gU OGx+ 0Gx O--t- + ~ + 0----7 = 0, (25) where the split fluxes Gx+ and Gx- are given by equation (24). It will be shown later in Section 3.5 that the Jacobians [aGx+/au] and [OGx-/OU] have all real positive and real negative eigenvalues, respectively. WebAs 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.
