Wall-mounted and strut-mounted microphones placed in the flow field are both sensitive to installation, placement, and flow-related effects. Therefore, it is advantageous to place the microphone sensors outside of the ducting of the turbomachine while also accounting for the acoustic characteristic of the ducting. In this paper, a ducted low-speed axial flow fan is investigated with the acoustically transparent duct (ATD) and the phased array microphone (PAM) Rotating Source Identification (ROSI) beamforming techniques at design and off-design conditions. The combination of these methods is capable of identifying the dominant sound sources of the fan in a non-intrusive approach at stall condition, pre-stall operation, design condition, and part-load operating condition as well.}, year = {2023}, eissn = {2048-4003}, pages = {625-638}, orcid-numbers = {Lendvai, Bálint/0000-0003-3741-2001; Benedek, Tamás/0000-0001-8057-3156} } @CONFERENCE{MTMT:34069787, title = {Preliminary case studies to acoustics-based condition monitoring of industrial fans}, url = {https://m2.mtmt.hu/api/publication/34069787}, author = {Tóth, D. and Divinyi-Zsoldos, T. and Lendvai, Bálint and Vad, János}, booktitle = {15th European Conference on Turbomachinery Fluid Dynamics and Thermodynamics 2023, ETC 2023}, doi = {10.29008/ETC2023-123}, unique-id = {34069787}, year = {2023}, orcid-numbers = {Vad, János/0000-0001-5589-1603} } @CONFERENCE{MTMT:34069781, title = {Application of a higher-order vortex identification method for quantifying the tip leakage vortex wandering in a low-speed axial fan case study}, url = {https://m2.mtmt.hu/api/publication/34069781}, author = {Lendvai, Bálint and Benedek, Tamás}, booktitle = {15th European Conference on Turbomachinery Fluid Dynamics and Thermodynamics 2023, ETC 2023}, doi = {10.29008/ETC2023-231}, unique-id = {34069781}, year = {2023}, orcid-numbers = {Lendvai, Bálint/0000-0003-3741-2001; Benedek, Tamás/0000-0001-8057-3156} } @article{MTMT:34046146, title = {Data-driven aerodynamic models for aeroelastic simulations}, url = {https://m2.mtmt.hu/api/publication/34046146}, author = {Lelkes, János and Horváth, Dávid András and Lendvai, Bálint and Farkas, Balázs and Bak, Bendegúz Dezső and Kalmár-Nagy, Tamás}, doi = {10.1016/j.jsv.2023.117847}, journal-iso = {J SOUND VIB}, journal = {JOURNAL OF SOUND AND VIBRATION}, volume = {564}, unique-id = {34046146}, issn = {0022-460X}, year = {2023}, eissn = {1095-8568}, orcid-numbers = {Lelkes, János/0000-0002-6205-4923; Lendvai, Bálint/0000-0003-3741-2001; Bak, Bendegúz Dezső/0000-0003-1378-875X; Kalmár-Nagy, Tamás/0000-0003-1374-2620} } @article{MTMT:33687613, title = {Aeroacoustic investigation of airfoil profiles in turbulence at moderate Reynolds numbers involving the phased array microphone technique and the ANOVA statistical method}, url = {https://m2.mtmt.hu/api/publication/33687613}, author = {Lendvai, Bálint and Benedek, Tamás and Balla, Esztella Éva}, doi = {10.1142/S0219477523500323}, journal-iso = {FLUCT NOISE LETT}, journal = {FLUCTUATION AND NOISE LETTERS}, volume = {22}, unique-id = {33687613}, issn = {0219-4775}, year = {2023}, eissn = {1793-6780}, orcid-numbers = {Lendvai, Bálint/0000-0003-3741-2001; Benedek, Tamás/0000-0001-8057-3156; Balla, Esztella Éva/0000-0001-6617-4474} } @inproceedings{MTMT:33128380, title = {Study on the effect of sudden duct diameter change on the performance of an axial flow fan}, url = {https://m2.mtmt.hu/api/publication/33128380}, author = {Lendvai, Bálint and Benedek, Tamás}, booktitle = {Proceedings of Conference on Modelling Fluid Flow (CMFF'22)}, unique-id = {33128380}, year = {2022}, pages = {504-511}, orcid-numbers = {Lendvai, Bálint/0000-0003-3741-2001; Benedek, Tamás/0000-0001-8057-3156} } @article{MTMT:32497448, title = {Combined acoustic and aerodynamic investigation of the effect of inlet geometry on tip leakage flow noise of free-inlet free-exhaust low-speed axial flow fans}, url = {https://m2.mtmt.hu/api/publication/32497448}, author = {Benedek, Tamás and Vad, János and Lendvai, Bálint}, doi = {10.1016/j.apacoust.2021.108488}, journal-iso = {APPL ACOUST}, journal = {APPLIED ACOUSTICS}, volume = {187}, unique-id = {32497448}, issn = {0003-682X}, year = {2022}, eissn = {1872-910X}, orcid-numbers = {Benedek, Tamás/0000-0001-8057-3156; Vad, János/0000-0001-5589-1603; Lendvai, Bálint/0000-0003-3741-2001} } @CONFERENCE{MTMT:31990690, title = {Aeroelasztikus szárnymodell numerikus vizsgálata}, url = {https://m2.mtmt.hu/api/publication/31990690}, author = {Lendvai, Bálint and Lelkes, János}, booktitle = {XXIX.
