The Aerodynamics and Acoustics Facility (AAF) is one of the University's central research facilities, supporting local institutions and industries with their research and development needs. The low-speed wind tunnel and large anechoic and reverberation chambers, unique to the Greater Bay Area, enable large-scale experiments of research and consultancy projects. Specialist measurement, analysis, and training services are also available.
 
The AAF is developing the Hong Kong's largest acoustic-fluids laboratory. This laboratory will house large-scale anechoic and reverberation chambers, as well as a high-speed acoustics-fluids test rig.
The facility was officially named the Aerodynamics and Acoutics Facility (AAF) as it reflects the new and advanced capabilities of the facility better.
The new wind tunnel's advanced capabilities apply to serveral emerging industries in Hong Kong and the Greater Bay Area, such as performance sports, urban air mobility, and green energy.
The University Council approved the facility's redevelopment for a brand-new, multi-functional wind tunnel facility and the Hong Kong's largest acoustics and fluids testing laboratory.
The facility completed consultancy and research projects for various Hong Kong civil engineering establishments. The facility also developed several research graduates and contributed to various Hong Kong landmarks.
The Hon. Tung Chee Hwa, Chief Executive of Hong Kong SAR, the Chancellor of HKUST, and The Hon. Michael D. Kadoorie, Chairman of CLP Holdings, opened the Wind/Wave Tunnel Facility (WWTF) on 9th June 2000. In addition to the University funding, CLP generously donated $10 million.
