论文摘要
在这项工作中，我们得出了一组紧凑的分析公式，这些公式表达了三维声辐射扭矩（ART），该公式施加在嵌入在流体中并被任意声学的任意形状粒子上的粒子上。该公式可直接计算来自Sapozhnikov和Bailey引入的基于角光谱的光束形状系数[J。声音。 Soc。是。 133，661（2013）]和部分波系数。当在源平面中知道声场时，它特别适合确定在粒子上施加的艺术。
In this work, we derive a set of compact analytical formulas expressing the three-dimensional acoustic radiation torque (ART) exerted on a particle of arbitrary shape embedded in a fluid and insonified by an arbitrary acoustic field. This formulation enables direct computation of the ART from the angular spectrum based beam shape coefficients introduced by Sapozhnikov and Bailey [J. Acoust. Soc. Am. 133, 661 (2013)] and the partial wave coefficients. It is particularly well suited to determine the ART exerted on a particle when the acoustic field is known in a source plane.
