Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishAn interface-capturing model for relativistic two-fluid flow is presented. The flow equations are the bulk-fluid equations, combined with particle number and energy-momentum tensor equations for one of the two fluids. The latter equations, i.e. the ones describing one component of the mixture, contain source terms, accounting for the energy and momentum exchanges between the species. The fluid model enables the derivation of an exact expression for these source terms. Weak discontinuities propagating into this relativistic two-fluid system are examined and, moreover, expressions for their speeds of propagation are obtained.
