This paper presents a method for modelling interfacial mass transfer in Interface Capturing simulations of two-phase flow with phase change. The model enables mechanistic prediction of the local rate of phase change at the vapour-liquid interface on arbitrary computational meshes and is applicable to realistic cases involving two-phase mixtures with large density ratios. The simulation methodology is based on the Volume Of Fluid (VOF) representation of the flow, whereby an interfacial region in which mass transfer occurs is implicitly identified by a phase indicator, in this case the volume fraction of liquid, which varies from the value pertaining to the "bulk" liquid to the value of the bulk vapour. The novel methodology proposed here has been implemented using the Finite Volume framework and solution methods typical of "industrial" CFD practice. The proposed methodology for capturing mass transfer is applicable to arbitrary meshes without the need to introduce elaborate but artificial smearing of the mass transfer term as is often done in other techniques. The method has been validated via comparison with analytical solutions for planar interface evaporation and bubble growth test cases, and against experimental observations of steam bubble growth.

我们应用浸没边界（或IB）的方法来模拟变形和分离的周期性阵列的壁约束的生物膜菌落响应于线性剪切流。生物膜材料被表示为沿着生物膜区域的三角测量的边缘放置的胡克弹簧的网络。通过使用Williams、Fauci和Gaver开发的流体应力跳跃方法计算作用于生物膜菌落的界面剪切应力、升力和阻力[Disc.康丁Dyn. Sys. B 11（2）：519-540，2009]，具有其排除过滤器的修改版本。我们的分离标准是基于一个新的概念的平均等效连续应力张量定义在每个IB点的生物膜，然后用于确定相应的冯米塞斯屈服应力;无论这个屈服应力超过一个给定的临界阈值的连接到该节点被切断，从而发出信号的分离事件的发生。为了捕捉的变形和分离行为的生物膜菌落在不同的生长阶段，我们考虑了一个家庭的四个生物膜形状与不同的纵横比。我们的数值模拟集中在弱生物膜的行为（具有相对较低的屈服应力阈值），并调查功能的流体-结构相互作用，如最大剪切力和阻力增加的位置。这项工作的最重要的结论是，在生物膜模型中，仅基于界面剪切应力的常用分离策略在应用于弱生物膜的剪切诱导分离的研究时可能导致不正确或不准确的结果。我们的分离策略的基础上等效连续应力提供了一个统一的和一致的IB框架，处理脱落和侵蚀模式的生物膜分离，并与许多其他连续的生物膜模型中采用的策略是一致的。
