This paper presents an overview of the characteristics potentially influencing the profile vortex shedding (PVS) phenomenon being relevant in noise and vibration of low-speed axial fan rotor blades. Dimensional analysis has been applied to explore the essential dimensionless quantities in a systematic and comprehensive manner. On this basis, limitations have been established, and simplifying assumptions have been set up in terms of PVS investigation. Groups of dimensionless characteristics playing a role in the semi-empirical model for predicting the PVS frequency were identified. The available semi-empirical model and its unique features related to the measurement evaluation methodology and Reynolds number dependence have been outlined. The presented comprehensive analysis provides guidelines from the perspective of transferability of the literature data on PVS from steady, isolated blade profile models to low-speed axial fan rotors. It also results in the formulation of objectives of future research related to PVS.

本文概述了可能影响与低速轴流风扇转子叶片的噪声和振动相关的轮廓涡旋脱落 (PVS) 现象的特性。已应用量纲分析以系统和全面的方式探索基本的无量纲量。在此基础上，建立了局限性，并在 PVS 调查方面建立了简化假设。确定了在预测 PVS 频率的半经验模型中发挥作用的无量纲特征组。已经概述了可用的半经验模型及其与测量评估方法和雷诺数相关性相关的独特功能。所提出的综合分析从 PVS 文献数据从稳定、孤立的叶片轮廓模型到低速轴流风扇转子的可转移性的角度提供了指导。它还导致制定与 PVS 相关的未来研究目标。
