- July 2025 -- Prof. Yang was invited to give a lecture, titled 'The interdisciplinary study on animal locomotion mechanics and flow acoustics' at the 4th National Conference on Aeroacoustics and its Control Technologies in Xi'an, Shaanxi. Also, EFD2 ( in Dublin, Ireland.
- Aug 20-23, 2024 -- Attended the annual conference of the Society of Engineering Science (SES) held in Hangzhou, the 2024 SES Annual Technical Meeting. This conference was the first time it was held in China, attracting over 1500 participants. Dr. Yang presented a talk titled "Flow-induced sound generated by bio-inspired swimmers" in the session on Bio-fluid and Bio-inspired Fluid Mechanics, which garnered attention from peers. During this time, I also visited the School of Engineering at Westlake University, relevant laboratories at Zhejiang University, and took a brief tour of West Lake.

- Aug 2024 -- Dr. Yang, as the principal investigator, has been granted approval and funding for the National Natural Science Foundation's General Program, titled "Flow-induced acoustics mechanisms and scaling law in bio-inspired quiet swimming," with a funding amount of 520,000 Yuan. The duration of the funding is from January 2025 to December 2028, under the project number 12472266. This project would focus on the acoustic generation mechanism and control characteristics of bio-inspired swimming. The essential reasons of the silence of natural organisms swimming would be explored, and the fluid-solid-acoustic coupling mechanism of biological motion and the mystery of flow and acoustic control need to be deeply understood, which may lead to forward-looking new concepts and new enlightenment for biomimetics.
- Feb 2024 -- Acta Mechanica Sinica has published our article online, "Hybrid approach for simulating flow-induced sound around moving bodies based on ghost-cell immersed boundary method". This work presents in detail the numerical simulation method of moving body flow vocalization (IBM-APE) and the sound field properties of a range of flow-generated sound fields, such as flapping and undulatory swimming, including single and multiple (tantem) foils. This work lays the foundation for exploring the widespread scientific problem of biomimetic flow-induce noise, and can provide a solid support of fluid mechanics for biologists (bio-acoustics) and biomimetic vehicles development and design with quietness. It can also promote the CFD and CAA simulation to play a greater role in the fluid-solid-acoustic coupling multidisciplinary, multi-physical interaction mechanism and bionic acoustics reduction design. More biomimetic flow-generated acoustics mechanisms by moving body need to be investigated. See Fulltext for details.
