Abstract

In this paper, sound absorption and scattering in suspensions with rotational particle motion is analyzed. Such rotational (angular) oscillations are possible if the particle’s center of mass is shifted with respect to the center of buoyancy. In such suspensions, there is specific sound attenuation and scattering. These effects can be used in problems of diagnosing suspensions in natural environments and technological processes, as well as in creating metamaterials.

声波在含旋转自由度粒子悬浮液中的传播和散射

本文分析了具有旋转粒子运动的悬浮液中的吸声和散射问题。如果粒子的质心相对于浮力中心移动，这种旋转（角）振荡是可能的。在这种悬浮液中，有特定的声音衰减和散射。这些效应可以用于诊断自然环境和技术过程中的悬浮液问题，以及创建超材料。
