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.}, keywords = {Dimensional analysis; fan noise; Vortex shedding; low-speed axial fan; moderate Reynolds number; blade vibration}, year = {2021}, eissn = {2041-2967}, pages = {349-363}, orcid-numbers = {Vad, János/0000-0001-5589-1603} } @inproceedings{MTMT:31827513, title = {Experiment-Based Preliminary Design Guidelines for Consideration of Profile Vortex Shedding From Low-Speed Axial Fan Blades}, url = {https://m2.mtmt.hu/api/publication/31827513}, author = {Daku, Gábor and Vad, János}, booktitle = {Proceedings of the ASME Turbo Expo 2020}, doi = {10.1115/GT2020-14214}, unique-id = {31827513}, year = {2020}, pages = {1-13}, orcid-numbers = {Vad, János/0000-0001-5589-1603} }
