Ultrasonic Attenuation of High Concentration of Micron Particle Clouds

Abstract

This paper presents the simulation and experiment about the attenuation characteristics of ultrasound in micron particle clouds. Firstly, several models that have been used in the suspension concentration measurement are analyzed. Then the numerical simulations are conducted to try to establish the relationship between the consciousness, particle size and the frequency. Finally, an experiment is conducted to verify whether the attenuation of ultrasound in micron particle clouds follows the simulations' relusts. The results of numerical simulations and the experiment both show that the intensity of ultrasound has a positive correlation with the consciousness, but the relationship between the attenuation and particle size is still uncertain for lack of experimental data. At present, research is still in ongoing.
