摘要
目前针对气浮过程的CFD-PBM数值计算方法中往往仅考虑气泡聚并行为,而忽略其破碎行为。为了验证气浮过程中仅考虑气泡聚并行为的数值计算方法准确性,在ANSYS Fluent平台使用CFD-PBM耦合方法针对科莫微尺度和气泡直径的分布规律进行了研究,得出气浮接触区大部分流域当中科莫微尺度均大于气泡直径,因此验证了针对气浮池接触区中气泡聚并行为数值计算时忽略气泡破碎行为的准确性。
The current CFD-PBM numerical calculation methods for the air flotation process often only consider the bubble coalescence behavior, but ignore the breakage behavior. In order to verify the accuracy of the numerical calculation method that only considers the bubble aggregation behavior in the air flotation process, the CFD-PBM coupling method was used on the ANSYS Fluent platform to study the bubble diameter and the Kolmogorov microscale distribution, it was concluded that the Kolmogorov microscale in most of the watersheds in the air flotation contact area was larger than the bubble diameter. Therefore, the accuracy of ignoring bubble breakage behavior in the numerical calculation of bubble movement in the contact area of the air flotation tank was verified.
