摘要 为了探究煤层裂隙通道壁面吸附气泡与运移气泡间的相互作用机理,本研究基于不同尺寸气泡间内部存在压力差的原理,通过建立气液两相流气泡运移数值模型,模拟大气泡与裂隙通道壁面吸附小气泡间作用行为,剖析气泡间相互作用原理,讨论不同流速以及不同气泡间间距条件下吸附气泡的行为特征、解吸效率以及运移规律。结果表明,体积较大气泡内部压力差较小气泡大,大气泡易与小气泡发生聚并;受流速的影响,表面张力的增加致使气泡破裂,裂隙通道内壁面吸附瓦斯气泡驱替量呈先增加后减少趋势;气泡间相互作用,最佳气泡间间距为0.3 ~ 0.5 mm。

Abstract :In order to explore the interaction mechanism between adsorbed bubbles and migrating bubbles on the wall of coal seam fracture channel, based on the principle of pressure difference between bubbles of different sizes, a numerical model of bubble migration in gas-liquid two-phase flow was established to simulate the interaction between large bubbles and adsorbed small bubbles on the wall of fracture channel. The principle of interaction between bubbles was analyzed, and the behavior characteristics, desorption efficiency and migration law of adsorbed bubbles under different flow rates and different bubble spacing were discussed. The results show that the internal pressure difference of large bubbles is larger than that of small bubbles, and large bubbles are easy to coalesce with small bubbles. Under the influence of flow velocity, the increase of surface tension leads to the rupture of bubbles, and the displacement amount of adsorbed gas bubbles on the inner wall of fracture channel increases first and then decreases. The optimal spacing between bubbles is 0.3 ~ 0.5 mm.
