一种集成风墙与低速风洞的系统
By integrating a wind wall and a low-speed wind tunnel into a system, the system utilizes a movable wind wall to pre-accelerate the recirculating airflow in front of the main fan, thus solving the problems of poor airflow quality and high operating costs in existing technologies and achieving low-cost, high-efficiency multi-scenario aerodynamic testing.

AI Technical Summary
Existing wind wall systems generate poor airflow quality, making it difficult to meet the requirements of high-precision aerodynamic testing. Low-speed wind tunnels, on the other hand, have high operating power and cost, making them unsuitable for frequent start-stop and flexible switching, and unable to meet the needs of multiple scenarios.
Design a system integrating a wind wall and a low-speed wind tunnel, including a test hall, a recirculation tunnel, a moving mechanism, and a movable wind wall. The movable wind wall pre-accelerates the recirculation airflow in front of the main fan, reducing the power requirement of the main fan, and the wind wall can be used independently for control testing when needed.
It realizes the integrated application of wind walls and low-speed wind tunnels, reduces the construction cost of wind tunnels, meets different aerodynamic testing needs, balances performance and cost-effectiveness, and provides a stable and uniform flow field and low background noise environment.
