Investigation of Suspended Sediment Properties based on Scholte wave

摘要

The propagation of the Scholte wave at liquid/solid interface is studied to measure the suspended sediment properties. Based on ultrasonic suspension models, i.e. Utrick, Utrick-Ament, HT and Mcclements, the Scholte wave propagation characteristics are analyzed at the interface between Sediment concentration two-phase fluid and porous medium solid. The relationship between Scholte velocity and two-phase fluid's properties, e.g., dispersion, volume content, particle size are discussed. The Scholte wave propagation and signal are obtained by simulation, and the obtained Scholte wave velocity are in accord with Utrick-Ament and HT mode. The proposed work is practically feasible and of great scientific and technological importance in sediment research.
