Abstract The existing viscous and incompressible theory of isothermal sound propagation and attenuation in suspensions considers solid particles which are infinitely viscous. We extend the theory by applying the amended Coriolis flowmeter “bubble theory”. Here, the drag force is a function of both the fluid and particle Stokes numbers and the particle-to-fluid ratio of the dynamic viscosity (Galindo and Gerbeth, 1993). Aerosol and hydrosol examples are presented and differences between the original and extended theories are discussed.

修正的科里奥利流量计“气泡理论”在气溶胶和水溶胶中声音传播和衰减中的应用

摘要 悬浮液中等温声传播和衰减的现有粘性和不可压缩理论考虑了无限粘性的固体颗粒。我们通过应用修正的科里奥利流量计“气泡理论”扩展了该理论。在这里，阻力是流体和粒子斯托克斯数以及动态粘度的粒子与流体比的函数（Galindo 和 Gerbeth，1993）。介绍了气溶胶和水溶胶示例，并讨论了原始理论和扩展理论之间的差异。
