| Abstract: | This paper concentrates on the wave motion at the
interface of viscous compressible fluid half-space
and homogeneous isotropic, generalized thermoelastic
diffusive half-space.
The wave solutions in both the fluid and thermoelastic diffusive
half-spaces have been investigated; and the complex dispersion equation
of leaky Rayleigh wave motion have been derived. The
phase velocity and attenuation coefficient of
leaky Rayleigh waves have been computed from the complex
dispersion equation by using the
Muller's method. The amplitudes of displacements, temperature change and
concentration have been obtained. The
effects of viscosity and diffusion on phase velocity and
attenuation coefficient of leaky Rayleigh waves motion for
different theories of thermoelastic diffusion have been depicted
graphically. The magnitude of heat and mass diffusion flux vectors
for different theories of thermoelastic diffusion have also been
computed and represented graphically. |
