稀疏固液两相流中空泡云的振动研究

A Study on the Oscillation of the Cloud of Bubbles in a Dilute Solid Liquid Two Phase Flow

建立了空泡云在稀疏固液两相流中振动的控制方程组，由小扰动理论和声学的方法求出了空泡在稀疏固液两相流中发生体积振动时声压传播的解析结果，分析了空泡云中空泡的大小、数量和混合流体中含气量、固体颗粒对空泡云振动的影响．

The control equations for the oscillation of the cloud of bubbles in a dilute solid liquid two phase flow have been worked out, and the analytical result of the sound pressure radiated from a cloud of bubbles oscillating in dilute solid liquid two phase flow are derived with the perturbation theory and the acoustic method. The influences of the number and size of the bubbles of the gas content in the mixture and of the solid particles on the oscillation of the cloud of bubbles are analyzed.
