BUBBLE COLLAPSE IN SOLID-LIQUID TWO-PHASE FLUID
-
摘要: 本文导出了固液两相流体中球空泡溃灭的运动方程,计算并讨论了空泡溃灭过程中的颗粒运动和颗粒对空泡溃灭的影响,得到了固相浓度、颗粒尺寸等因素与空泡溃灭之间的定性关系。在分析过程中,考虑了液体与固体颗粒之间的阻力耦合作用。Abstract: Equation of motion for bubble collapse in solid-liquid two-phase fluid have been derived, in which the resistance coupling effects between the liquid and solid particles have been considered. The motion of particles during the bubble collapse and the effects of particles on bubble collapse have been calculated and discussed. Qualitative relations between the concentration and the size of the particles and the rate of bubble collapse have been obtained.
