本文提出了一种新的统一的单场公式，用于局部体积变化的界面传质的流体体积模拟。通过与文献中称为连续物种转移的先前模型的比较，我们改进的模型使用跨界面的局部传质的单场制剂，使我们能够考虑到由非稀释物种转移引起的局部体积变化。数值模型，在我们的内部OpenFOAM为基础的模拟器中实现，通过比较在1D和2D的解析解，并在3D的半解析解进行验证。实施的方法首先适用于调查竞争质量传递在一个无限的圆柱。然后，我们模拟了低施密特数下单组分上升气泡的收缩。数值模型被证明是非常适合调查舍伍德数和现有的相关性在流体界面处的传质。(C)2019爱思唯尔公司All rights reserved.
This paper presents a novel unified single-field formulation for Volume-Of-Fluid simulation of interfacial mass transfer with local volume changes. By comparison with the previous models referred as Continuous Species Transfer in the literature, our improved model uses a single-field formulation of the local mass transfer across the interface, enabling us to take into account local volume changes induced by non-dilute species transfer. The numerical model, implemented in our in-house OpenFOAM-based simulator, is validated by comparison with analytical solutions in 1D and 2D, and a semi-analytical solution in 3D. The implemented approach is first applied to investigate competing mass transfer in an infinite cylinder. We then simulate the shrinking of a single-component rising bubble at low Schmidt number. The numerical model is shown to be well adapted to investigate Sherwood numbers and existing correlation for mass transfer at fluid interfaces. (C) 2019 Elsevier Inc. All rights reserved.
