Governing equations for two-phase compressible flow with different phase pressures and temperatures are presented, the derivation of which is based on the formalism of thermodynamically compatible ...

The mathematical model of wave propagation can involve different types of partial differential equations (PDEs) depending on the physical context that one wants to study. For instance, propagation of ...

Abstract. For a two–dimensional time nonlinear hyperbolic equation with a power nonlinearity, a threshold exponent depending on the space dimension is presented. Furthermore, the analysis is extended ...
