摘要:
静水中的上升气泡会诱导产生流场,进而影响到水中颗粒物的运动,这一气-液-固三相流动的问题在水处理领域中大量存在,需要建立行之有效的方法来加以研究.首先采用相场方法模拟了气-液两相流动,刻画了气泡在静水中上升、膨胀、变形的动态过程,得到了气泡上升所诱导的外部流场;随后将颗粒引入气-液两相流场,考虑颗粒在受到重力、浮力、流体Stokes力作用下的运动行为,从而建立了静水中上升气泡作用下颗粒运动的力学模型.在此基础上,研究了颗粒的粒径、分布的展向位置、垂向位置等参数对颗粒运动的影响.通过与滤池反冲洗中滤料颗粒跃动实验结果的比较,可以认为数值模拟很好地反映了上升气泡对颗粒运动的影响,即颗粒运动的微观机制.
Abstract:
Rising bubble will induce flow field, and then affect the movement of particles in static water. There are many gas-liquid-solid three-phase flow problems in the water treatment field, for which we need to establish an effective method of study. This paper used the phase field method to simulate the gas-liquid two phase flow. Two important results, the dynamic processes of bubble rising, expansion and deformation and the induced external flow field of this rising bubble, were obtained from simulation directly. Particles were introduced into this system and their movement under the gravity, buoyancy and Stokes force was investigated. So far, the model of particle movement under the action of rising bubble was established. On this basis, we studied the effect of different parameters, including particle size, the transverse distribution and the vertical position was studied. To compare with the previous experiment about the particles movement in backwash filter, it can be seen that the numerical simulation reflects the microscopic mechanism of particle movement by rising bubble rise very well
