| Abstract: | In this paper,we established an equation of thermoelastic wave equation in thermal elastic fluid medium.It is pointed out that two kinds of waves can propagate in the medium possibly.The basic concept and characteristics of the thermoelastic P wave have been established.The reflection problem of thermoelastic waves in a liquid-solid interface has been studied.In addition,the reflection coefficient,the expression of the transmission coefficient,the character of reflective thermal elastic P wave and the type of SVS wave have also been given. |
