Analog gravity in nonisentropic fluids

29 May 2018 Bilić Neven Nikolić Hrvoje

The analog acoustic metric has been originally derived for adiabatic acoustic perturbations propagating in an isentropic irrotational ideal fluid. In the framework of a Lagrangian hydrodynamic description we demonstrate that under certain conditions the usual acoustic metric can be derived for nonisentropic fluids... (read more)
