The Aerodynamics Acoustics & Noise control Technology Centre (AANTC) is located at the Hong Kong University of Science and Technology, which has a strong international reputation and consistently ranks high among major engineering institutes around the world. In the 2013-14 Times Higher Education World University Rankings in Engineering and Technology, HKUST was ranked No. 1 in Greater China and 21st globally. AANTC, led by Professor Xin Zhang, brings together academic staff, research fellows and PhD students using state-of-the-art computer simulations and advanced anechoic wind tunnel testing to develop new computational methods, noise prediction methods, noise reduction concepts, and provide engineering solutions for the industry. The centre possesses high-order in-house computational aeroacoustic codes and various acoustic and aerodynamic test facilities.
Professor Xin Zhang attended and presented on inter.noise 2019 conference in Madrid on latest researches conducted in AANTC, including turbulence-aerofoil leading edge noise (Link) and the design of Helmholtz resonators on noise reduction (Link).
PhD students of AANTC attended and presented at 25th AIAA/CEAS Aeroacoustics Conference in Delft, Netherlands led by Professor Zhang. Students presented their own works and shared their research results with scholars all over the world.
Professor Zhang is collaborating with HKSI to help enhance elite cyclists' performance aiming at the Tokyo 2020 Olympics. The collaboration received a donation from Mr Adam KWOK, Executive Director of SHKP. Head cycling coach Mr SHEN Jinkang and the world champion LEE Wai-sze are also highly involved in the program and will provide professional advice on performance improvement.
Head coaches from HKSI and the delegation from Shanghai administration of sports visited AANTC on 25/01/2019. Professor Zhang gave a detailed introduction to research facilities and projects going on in Performance sports engineering (PSE). To study the aerodynamic effect in racing technology, PSE aims at using the most advanced computational technology and wind tunnel facilities to improve the performance of athletes and vehicle dynamics.
The chairman and president of AVIC visited AANTC in the company of Prof. Xin Zhang and Prof. Wei Shyy. Students from AANTC gave demonstrations of their latest research works, and the academic output from the centre was highly spoken of. The cooperation between AVIC and HKUST starts from 2012 and remarkable success has been achieved especially in aerodynamic and acoustic researches.

Performance Sports Engineering focuses on the improvement from aerodynamic performance using CFD or experiments. The research is being conducted on track and road bicycle, racecars using advanced hybrid method combining both high-performance computing and high accuracy experimental measurement. The group is also working with teams in cutting-edge race car industries in the world.
Details of the research.
The in-house ENVironmental Acoustic Ray-tracing Code (EnvARC) at the AANTC generates acoustic maps using generalized acoustic sources, generic terrain and building models with user-defined impedances, and resolves the effects of atmospheric sound absorption and refraction. The inputs consist of the noise source and environmental scenario models as well as the observer positions. The output is the noise exposure map for noise evaluation and abatement.
Details of the research.
A new acoustic analogy is developed using an indirect acoustic variable, which filters the non-acoustic components in a turbulent flow. An innovate method is employed to solve the resultant third order wave equation. The sound extrapolation method based on the new acoustic analogy can compute the far-field directivities using single off-body integration surface without spurious wave contamination.

Xin Zhang holds a PhD degree in fluid mechanics from the Cambridge University, UK and BEng in aerospace engineering from Beijing University of Aeronautics and Astronautics, China. He is a fellow of the Royal Aeronautical Society and associated fellow of American Institute of Aeronautics and Astronautics. He is currently the Swire Professor of Aeropace Engineering at Hong Kong University of Science and Technology.
Dr Zhang conducts research and lectures in aerodynamics and aeroacoustics, in particular aircraft aerodynamics and noise. He has conducted experimental and computational research in the area of unsteady aerodynamics, ground effect aerodynamics, aeroacoustics, and aircraft noise. He is an authority in the area of aircraft noise including both airframe and propulsive unit noise. He performed research in its understanding, developed novel and accurate numerical schemes for its prediction, devised methods for noise attenuation, and designed and constructed predictive codes based on physics for noise prediction which are being used by industry.
Dr Zhang has published over 200 papers including 95 archival papers. He has been an effective educator, establishing the first MSc course in racing car aerodynamics in the world at Southampton. To date, he has supervised nearly 50 PhD/EngD students as main supervisor; these students currently hold diverse positions in academia, aerospace and automotive industries, government, and other sectors.
