Abstract

Air-core vortexing phenomenon during draining of liquids from cylindrical vessels is of major interest because this phenomenon has significant impact in multiple engineering systems. The adverse effects created by vortex formation via air-core ingestion in the field of aerospace engineering, metal casting and hydraulic engineering demanded the need for air-core vortex suppression. From past few decades, researchers have come up with unique strategies to suppress vortexing phenomenon. As the first ever initiative, the current review classifies all the strategies reported in the literature and addresses the advantages and adverse effects of each strategy. Based on this classification, this review identifies vortex suppression strategies suitable for various engineering applications. The present review also investigates the contradictions and misinterpretations observed in the published results. Research gaps and major outcomes identified in this review are novel and are expected to give a fresh impetus for further research delivering new insights on the phenomenon of air core vortex formation aiding to develop new suppression strategies.

排液槽中兰肯涡形成的抑制：综述

在圆柱形容器排液过程中，空气芯涡现象引起了人们的广泛关注，因为这种现象对多种工程系统都有重要的影响。在航空航天工程、金属铸造和水利工程等领域，通过吸入空气芯形成涡流所产生的不利影响要求对空气芯涡流进行抑制。在过去的几十年里，研究人员提出了独特的策略来抑制涡旋现象。作为有史以来的第一个倡议，目前的审查分类所有的战略报道在文献和解决每个战略的优势和不利影响。在此基础上，本文综述了适用于各种工程应用的涡抑制策略。本综述还调查了在已发表的结果中观察到的矛盾和误解。本综述中发现的研究空白和主要成果是新颖的，有望为进一步的研究提供新的动力，提供对空气核心涡形成现象的新见解，有助于开发新的抑制策略。

期刊介绍： The European Journal of Mechanics - B/Fluids publishes papers in all fields of fluid mechanics. Although investigations in well-established areas are within the scope of the journal, recent developments and innovative ideas are particularly welcome. Theoretical, computational and experimental papers are equally welcome. Mathematical methods, be they deterministic or stochastic, analytical or numerical, will be accepted provided they serve to clarify some identifiable problems in fluid mechanics, and provided the significance of results is explained. Similarly, experimental papers must add physical insight in to the understanding of fluid mechanics.
