a delegation of government officials led by carrie lam, chief executive of china's hong kong special administrative region (hksar), visited genertec caeri during its official trip to southwest china's chongqing municipality from sept. 24 to 25, which was also lam's first official visit to chongqing. these hksar government officials watched caeri aawt vehicle flow visualization and full width frontal impact test at genertec caeri.

with an investment of 550 million yuan (about $85.2 million), the automobile wind tunnel of genertec caeri was completed and put into operation in 2019. it mainly comprises an aerodynamic-acoustic wind tunnel, an environmental wind tunnel, an environmental cabin and a high-performance simulation computing platform.

equipped with the core competence in providing technical services for major automobile makers in the world, the automobile wind tunnel has greatly made up for the lack of research resources for automobile wind tunnel tests in china.

caeri aawt vehicle flow visualization conducted in wind tunnel lab is an indispensable part for improving automobile aerodynamic performance. it helps engineers better grasp the airflow characteristics at the bottom of vehicles so as to further improve automobiles' aerodynamic performance.

simulating frontal impact in the lab serves as the basis for analyzing and evaluating crashworthiness, or the occupant protection ability of automobiles during crashes.

genertec caeri has been focusing on evaluation of and research into tests on vehicle passive safety systems, and is able to conduct all relevant tests required by domestic standards and regulations. as china's first authorized unit of the euro ncap, it has played an important role in helping chinese car companies to expand their business overseas.

hong kong and chongqing enjoy broad space for cooperation in the application of sci-tech achievements, said lam, adding that she looks forward to closer collaboration between the two parties.
