综述了气泡流动直接数值模拟的研究现状，并介绍了一些最新的研究成果。基于单场公式的数值方法的发展，使得在足够长的时间内跟踪大量气泡的演变成为可能，从而可以获得流动平均性质的收敛统计。除了对均匀气泡流动的广泛研究之外，最近的研究有助于深入了解由于在湍流中注入气泡而减少阻力以及通道中层流多相流的两种流体建模。
The status of direct numerical simulations of bubbly flows is reviewd and a few recent results are presented. The development of numerical methods based on the one-field formulation has made it possible to follow the evolution of a large number of bubbles for a sufficiently long time so that converged statistics for the averaged properties of the flow can be obtained. In addition to extensive studies of homogeneous bubbly flows, recent investigations have helped give insight into drag reduction due to the injection of bubbles into turbulent flows and two-fluid modeling of laminar multiphase flows in channels.
