摘要/Abstract

摘要： 气泡沿斜面运动现象在工业生产中广泛存在,采用格子Boltzmann方法(LBM)研究单个气泡沿倾斜绝热表面的运动过程,考察气泡的初始直径、斜面倾角、Eotvos数(Eo)对气泡的变形和气泡形心与斜面垂直距离的影响,探讨相同初始直径的气泡沿斜面运动的稳定终态速度与倾角和Eo之间的关系。通过模拟得出气泡沿斜面的运动规律:斜面倾角越大,气泡前后端不对称性越大;气泡在上升过程中,形心轨迹与斜面保持平行;当倾角大于45°时,形心与斜面的垂直距离和Eo变化一致,当小于45°时,变化相反;相同初始直径气泡的稳定终态速度随倾角和Eo的增加而增加。

Abstract: Bubble moving along an inclined surface is a common phenomenon in industry.A single bubble rising along an inclined adiabatic surface was simulated with the lattice Boltzmann method(LBM).The influences of initial bubble diameter,inclined angle and Eotvos number on bubble deformation and the vertical distance between its centroid and the surface,were studied.Under the condition of fixed initial bubble diameter,the relationships between bubble terminal velocity,inclined angle and Eotvos number were also investigated.The simulation revealed that the asymmetry of bubble became significant with the increasing of inclined angle.During the rising process,the trajectory of bubble's centroid remained parallel to the surface.When the inclined angle was greater than 45°,the vertical distance between its centroid and the surface increased with the Eotvos number, while when it was less than 45°,the variation was the opposite.Besides,the bubble's terminal velocity increased with increasing inclined angle and Eotvos number for the same initial diameter.

Key words: lattice Boltzmann method, single bubble, inclined adiabatic surface, motion characteristic
