| 本文从粒子在行波场中的声散射出发，研究当声场中存在稀疏分布的多个粒子时粒子受到的声辐射力，并且给出了适用于声场中任意位置的粒子声辐射力计算公式。由于声辐射力为非线性力，当声场中存在多个粒子时，直接计算粒子受到的声辐射力非常复杂。本文的结果表明当声场中存在多个稀疏分布的粒子时，这一多粒子系统可以视为多个单独的双粒子系统的叠加，只需要分别计算各个双粒子系统的声辐射力就可以通过叠加得到声场中任意粒子的声辐射力。这一结果有助于利用声辐射力对微小粒子进行精细操控。 |
| 英文摘要: |
| In this paper, we study the acoustic radiation force of the particles when there are sparsely distributed particles in sound field, give the formula for calculating the acoustic radiation force of the particles in any position in sound field and make the simulation. Since the acoustic radiation force is nonlinear, it’s very complicated for us to calculate the acoustic radiation force directly. Our calculation results show that when the sound field contains multiple sparsely distributed particles, the multi-particle system can be decomposed into several independent two-particle systems. Only need to calculate the acoustic radiation force of each two-particle system respectively, we can get the radiation force of any particle by superposition. These results will help to fine control the microparticles with acoustic radiation force. |
