摘要

利用有限元软件COMSOL模拟了声波打在不同属性粒子上的散射现象

并且研究了粒子对声波的吸收

其中考虑了粘滞损失、热传导损失和散射。结论是不同属性粒子对声波的散射效果不同

而且不同属性粒子对声波的吸收也不同

其中阻抗越大

粒子对声波的吸收越小。

Abstract

The scattering phenomenon that sound waves hitting particles of the different properties is simulated by the finite element software COMSOL

and the particle absorbing sound waves is researched

which consider the viscous loss

heat loss and scattering. The conclusion is that the scattering effect of different attributes on acoustic is different

and different properties of particles absorbing sound waves are different

the greater the impedance of the particles is

the smaller the particle absorbing sound waves is.
