The present paper aims to study the phenomena of droplet entrainment from water pool. This phenomena could be either a consequence of boiling or depressurization. In a bubble column, droplets are released at the surface of the pool by bursting (in bubbly flow regime) or by detachment (in churn turbulent flow regime) depending of the hydrodynamics inside the pool. Eventually, these droplets are entrained by the streaming gas (superficial gas velocity) or settling down due to gravity.

Many experimental studies have been conducted, and several numerical simulations were performed to a better understanding of the phenomena of entrainment. Numerical simulation are a good tool to simulate an experiment due to limitations of data. To that end, CFD showed to be a good candidate to perform such a simulation, yet demand high computational performance and are time consuming. However, Lumped Parameter codes (LP) are widely used due to their simplicity and fast running, nevertheless, only provides qualitative and quantitative data. This paper gives a detailed review on the phenomena of entrainment covering experimental, analytical work. Relevant details on pool scrubbing are also provided for completeness purposes.

本文旨在研究水珠夹带现象。这种现象可能是沸腾或减压的结果。在气泡塔中，根据池内的流体力学，通过破裂（在气泡流态）或通过分离（在湍流流态），液滴在池的表面释放。最终，这些液滴被流动的气体夹带（表观气体速度）或由于重力而沉降。

已经进行了许多实验研究，并且进行了一些数值模拟以更好地理解夹带现象。由于数据的限制，数值模拟是模拟实验的好工具。为此，CFD被证明是执行此类仿真的理想选择，但要求较高的计算性能且非常耗时。但是，集总参数代码（LP）由于其简单性和快速运行而被广泛使用，但是，它仅提供定性和定量数据。本文详细介绍了夹带现象，涵盖了实验，分析工作。出于完整性目的，还提供了有关池清理的相关详细信息。
