本研究的目的是通过使用仿真软件包（FLUENT）揭示喷射制冷循环中蒸汽喷射器的流动和混合过程的复杂性。在本工作的第 1 部分中，蒸汽喷射器性能的 CFD 结果通过实验值进行了验证。验证通过后，本文能够分析蒸汽喷射器在工作条件和几何形状变化时的内部流动现象。使用CFD软件提供的应用程序，可以以图形方式创建模型喷射器的流动结构，并探索流动通道内的现象。 CID 方法被评估为表示蒸汽喷射器内部流动的有效工具。 (c) 2006 年 Elsevier Masson SAS。版权所有。
The aim of this study is to reveal the complication of the flow and the mixing process of a steam ejector used in a jet refrigeration cycle by using the simulation software package (FLUENT). In Part 1 of this work, the CFD results of the steam ejector's performance were validated with the experimental values. After the validation is satisfied, this paper is able to analyze the flow phenomena inside the steam ejector when its operating conditions and geometries were varied. Using the applications provided by the CFD software, the flow structure of the modeled ejectors could be created graphically, and the phenomena inside the flow passage were explored. The CID method was evaluated as an efficient tool to represent the flow inside a steam ejector. (c) 2006 Elsevier Masson SAS. All rights reserved.
