Abstract

Based on a balance equation for the energy density, an expression for the centrovelocity is derived which differs from the usual energy-flux velocity by a loss-flux term as a consequence of the presence of dissipation. In this part the expression is investigated for linear wave equations, in particular for first-order hyperbolic systems.
