Abstract
A model was established for the fluid - solid interface of semi-infinite medium, and the characteristic equation was established using the potential function. Applying line source at the fluid-solid interface, transform solution of displacement could be obtained, and time-domain solution could be evaluated through the inverse Fourier transform. Two kinds of ultrasound suspension model, UA and HT, were used to study and discuss the effect of sediment content to fluid-solid interface time-domain waveform. The results of two models have a good consistency. The sediment content have a great impact on the Scholte wave. With the increase of the sediment content, for Scholte wave, the velocity increases and the attenuation decreases.
