Abstract

The authors discuss dynamics of gas bubble and mineral particle in low-viscous fluid. The particle–bubble interaction model represents a system of associated differential algebraic equations. Dynamics of the disturbed system is described using the Lagrangian method. The model takes into account oscillations of bubble surface and attached solid cylindrical particle in the infinitive volume of perfect incompressible liquid. The capillary force retaining the particle on the bubble is governed by the meniscus shape which conditions the wetting angle. The Legendre series expansion is used to represent small axially symmetrical oscillations of the particle–bubble system. The potential and kinetic energies of the system are expressed in terms of the coefficient of this series. The resultant eddy-free velocity field allows including the viscosity effect with regard to the local rates of energy dissipation.

低粘度液体浮选中的颗粒-气泡行为
摘要 作者讨论了低粘性流体中气泡和矿物颗粒的动力学。粒子-气泡相互作用模型是一个相关微分代数方程系统。扰动系统的动力学用拉格朗日法描述。该模型考虑了完美不可压缩液体不定体积中气泡表面和附着固体圆柱形颗粒的振荡。将颗粒固定在气泡上的毛细力受半月板形状的制约,而半月板形状又是润湿角的条件。Legendre 列展开用于表示粒子-气泡系统的轴对称小振荡。系统的势能和动能用该级数的系数表示。由此得到的无涡流速度场允许在局部能量耗散率方面加入粘度效应。
