This paper presents a detailed and objective review of regenerative flow turbomachines, namely pumps, blowers and compressors. Several aspects of turbomachines like design and operating parameters, working principle, flow behaviour, performance parameters and analytical and Computational Fluid Dynamics (CFD) related details have been reviewed and summarized. Experimental work has been put in perspective and the most useful results for optimized performance have been presented. Consolidated plots of specific speed-specific diameter have been plotted which can be helpful in the early stages of design. Industrial outlook involving details of suppliers from various parts of the world, their product description and applications too are included. Finally, future research work to be carried out to make these machines widespread is suggested. This review is targeted at designer engineers who would need quantitative data to work with.

本文对再生流涡轮机（即泵，鼓风机和压缩机）进行了详细客观的综述。涡轮机的几个方面，如设计和运行参数，工作原理，流量特性，性能参数以及与分析和计算流体动力学（CFD）相关的细节，已经得到了综述和总结。已将实验工作放在了眼前，并提出了用于优化性能的最有用的结果。已绘制了特定速度-特定直径的合并图，这在设计的早期阶段可能会有所帮助。包括来自世界各地的供应商的详细信息，其产品描述和应用在内的工业前景也包括在内。最后，提出了使这些机器广泛使用的未来研究工作。
