On October 7th, the LVA was represented at the AeroAcoustics Research Consortium (AARC) Annual meeting by Prof. Julio Cordioli. 🚀 The professor presented the main results of an ongoing research project that uses high-fidelity simulations and experimental analysis to understand the effects of sheared flow on the acoustic impedance of liners. This project is developed in collaboration with Prof. Francesco Avallone from Politécnico de Torino, Italy, and is funded by the AARC. Founded in 2001 by NASA Glenn Research Center and industry partners, the AARC aims to advance technologies that reduce the environmental impact of noise produced by commercial aircraft. Current industrial partners include Airbus Commercial Aircraft, Honeywell Aerospace, Pratt and Whitney, Rolls-Royce Deutschland, and Raytheon Technologies Research Center. 🤝 Following this, Prof. Cordioli participated in the 2024 NASA Acoustics Technical Working Group and UAM Noise Working Group meetings, which took place at NASA Glenn Research Center, Cleveland, Ohio, from October 8th to 10th. These meetings provided a great opportunity to follow up on current research projects by the NASA Acoustic group and to discuss future research topics. 🔍

Recently, two articles were published by members of the LVA team! The articles have the titles (1) "A comparison of tonal-broadband decomposition algorithms for propeller noise" and (2) "Optimal impedance of a lined plane surface with inviscid sheared grazing flow". 🔎 Both were developed by pHd student Lucas A. Bonomo and Professor Julio Cordioli, along side researchers (1) Alysson K Colaciti, João Victor N. Fonseca and Leandro Simões; (2) André Mateus Netto Spillere and Edward James Brambley. 👨🏻💻 📄 The article (1) was published at the International Journal of Aeroacoustics, follow the link to read the full work: https://lnkd.in/dckX6HsG And article (2) was published at theJournal of Sound and Vibration, follow the link to read the full work: https://lnkd.in/dafMu8W6

Recently, the article "Towards an optimal design of acoustic Luneburg lenses” was published by LVA's professor Dr. Andrey M. da Silva, along side Mechanical Engineering student Victor M. Duarte! 📄 The work was published at the "Journal of the Acoustical Society of America" and presents the most recent results of the Laboratory's (LVA) promising research involving the study of acoustic lenses. 🔍 📄 Here’s the abstract about the work: Although the concept of acoustic Luneburg lenses was first proposed more than 50 years ago, its physical realization became feasible only in the last decade, owing to advancements in metamaterials research. Since then, numerous studies have explored the potential of these devices from the acoustic perspective. However, a comprehensive understanding of the mechanisms associated with the optimal performance of these lenses remains underexplored in the literature. This study conducts numerical investigations to identify parameters enhancing acoustic gain in Luneburg lenses. The analyses are conducted with the results obtained from a flattened Luneburg lens model based on the lattice Boltzmann method. Results, scaled with the Helmholtz number, He, indicate that the maximum acoustic gain occurs at He = 1.3, with performance sustained over a wide range of Helmholtz values. Analysis of surface impedance reveals underperformance for Helmholtz values below 0.5 due to viscous dissipation and above 2.0 due to Bragg reflections. These results provide a basis for evaluating the Helmholtz parameters that optimize the acoustic gain of Luneburg lenses. 📌 Follow the link to read the full article: https://lnkd.in/dsP8x7m4
