旋涡泵可以推动含固体的流体，因此被广泛应用，从废水输送到食品工业。尽管不断努力改进旋涡泵，但与传统的离心泵相比，它们仍然相对低效。为了寻找旋涡泵的优化设计方案，本文系统分析了几何参数变化对旋涡泵特性的影响，特别是对泵扬程、压力系数和最佳点运行效率的影响。为此，我们进行了广泛的文献检索，鉴定并整合了18篇文章和53项主要调查。这表明旋涡泵的工作原理尚不清楚。对旋涡泵基本工作原理的两种不同假设导致了设计原则的分歧。根据这一荟萃分析的结果，我们推断出更有效的旋涡泵设计的建议，并进一步强调旋涡泵的基本工作原理。
Vortex pumps can impel solid-containing fluids and are therefore widely applied, from wastewater transport to the food industry. Despite constant efforts to improve vortex pumps, however, they have remained relatively inefficient compared to conventional centrifugal pumps. To find an optimized design of vortex pumps, this paper provides a systematic analysis on experimental studies that investigated how variations in geometric parameters influence vortex pump characteristics, in particular the pump head, the pressure coefficient and the efficiency for best point operation. To this end, an extensive literature search was conducted, and eighteen articles with 53 primary investigations were identified and meta-integrated. This showed that it is not yet clarified how vortex pumps operate. Two different assumptions of the underlying operating principle of a vortex pump lead to diverging design principles. From the results of this meta-analysis, we deduce recommendations for a more efficient design of a vortex pump and emphasize further aspects on the underlying operating principle of a vortex pump.
