On a Rayleigh Structure in Temperature Waves

Abstract

The hyperbolic temperature wave is investigated as a Rayleigh-like wave that contains mixed transverse and longitudinal components. This allows the absolute ratio of the longitudinal to transverse interfering components to vary in space & time, with increasing the frequency of this wave. Such a variation is demonstrated, for the first time, to exhibit an initial smooth build up with increasing the frequency, to be followed by an asymptotic temporally oscillatory decay towards zero. A main result of this work is that heat transport can be enhanced by vibration only at low frequencies.
