对含有多个气泡的液体中的压力波传播进行了数值研究。我们使用 N 个球形气泡的运动方程模拟矩形管道中包含 10 个球形气泡的液体中的线性平面波传播。采用图像法计算刚性壁反射波的声压。结果表明，压力波在管道内含有10个球形气泡的液体中传播的相速度与声在均匀气泡液体中的低频速度非常吻合。
Pressure wave propagation in a liquid containing several bubbles is numerically investigated. We simulate liner plane wave propagation in a liquid containing 10 spherical bubbles in a rectangular duct with the equation of motion for N spherical bubbles. The sound pressures of the reflected waves from the rigid walls are calculated by using the method of images. The result shows that the phase velocity of the pressure wave propagating in the liquid containing 10 spherical bubbles in the duct agrees well with the low-frequency speed of sound in a homogeneous bubbly liquid.
