| Abstract: | An equation of motion for spherical bubbly oscillations in solid-liquid two-phase fluid, with the incorporation of the resistance coupling effects between the liquid and solid particles, is derived. The effects of particles on bubble motion and bubble wall pressure are analysed by using numerical methods. It is shown that bubble oscillation amplitude and bubble wall pressure are decreased when liquid contains solid particles. The large the solid particle concentration, the larger the effects of particles on bubble oscillation. When the solid particle concentration are the same, the smaller the sine of the particles, the larger the effects of the particles on bubble oscillation. |
