Singular perturbation theory of two-time scale expansions was developed in inviscid fluids to investigate the motion of single interface standing wave in a two-layer liquid-filled circular cylindrical vessel, which is subjected to a vertical periodical oscillation. It is assumed that the fluid in the circular cylindrical vessel is inviscid, incompressible and the motion is irrotational, a nonlinear...
In this study we consider linear thermoelastic wave propagation with second sound. We consider two theories; a theory based on the Maxwell-Cataneo relation and a linearized theory based on a simplified form of a generalization of classical thermoelasticity. We consider cylindrically and spherically symmetric longitudinal waves, and for both problems we obtain expressions for the initial discontinuities,...
