Efficient techniques have been developed, in the last decade, to achieve numerical solutions for the system of conservation laws that describe compressible inviscid flows. These techniques are founded on upwind formulations, such as the flux-vector or the flux-difference splitting. The high quality of the numerical results is related to the respect of the domains of dependence of propagating signals, a physical feature that is retained and preserved in the numerical procedure. The speed of sound plays a preminent role in describing the propagation of signals.
