摘要

This article reviews and analyzes a number of numerical methods to track interfaces in multiphase flows. Several interface tracking methods can be found in literature: the level-set method, the marker particle method, the front tracking method and the volume of fluid method (VOF) to name a few. The volume of fluid method has an advantage of being conceptually simple, reasonably accurate and phenomena such as interface breakup and coalescence are inherently included. Over the years a number of different techniques to implement the VOF method have been devised. This article gives a basic introduction to the VOF method and focuses on four VOF methods: flux-corrected transport (FCT) by Boris et al. [J.P. Boris, D.L. Book, Flux-corrected transport. I: SHASTA, a fluid transport algorithm that works, J. Comput. Phys. 11 (1973) 38-69], Lagrangian piecewise linear interface construction (L-PLIC) by van Wachem and Schouten [B.G.M. van Wachem, J.C. Schouten, Experimental validation of 3-d Lagrangian VOF model: bubble shape and rise velocity, AIChE 48 (12) (2002) 2744-2753], Compressive interface capturing scheme for arbitrary meshes (CICSAM) by Ubbink [O. Ubbink, Numerical prediction of two fluid systems with sharp interfaces, Ph.D. Thesis, Imperial College of Science, Technology and Medicine, 1997] and inter-gamma scheme by Jasak and Weller [H. Jasak, H.G. Weller, Interface-tracking capabilities of the InterGamma differencing scheme, Technical Report, Imperial College, University of London, 1995]. A detailed description of these schemes is given and implemented into an in-house fully coupled solver. Further, the performance of these schemes is examined employing a number of tests to analyze their strengths and weaknesses. Their advantages and limitations are discussed.

Schouten，3-d拉格朗日VOF模型的实验验证：气泡形状和上升速度，AIChE 48（12）（2002）2744-2753]，任意网格的压缩界面捕获方案（CICSAM），作者：Ubbink [O. Ubbink，具有尖锐界面的两个流体系统的数值预测，博士学位。论文，帝国理工学院和医学，1997年）和Jasak和Weller的伽玛间计划[H. Jasak，H.G. Weller，InterGamma差分方案的接口跟踪功能，技术报告，伦敦大学帝国学院，1995年]。给出了这些方案的详细说明，并将其实施到内部完全耦合的求解器中。此外，通过大量测试来分析这些方案的性能，以分析其优缺点。讨论了它们的优点和局限性。
