我们设计、建造了一个用于气溶胶研究的低成本风洞，并对2微米和0.46微米颗粒的气溶胶均匀性进行了评估。使用商用雾化器产生悬浮测试颗粒，并使用定制的四孔喷射器将气溶胶引入风洞。市售光学粒子计数器测量粒子浓度。两种流量下的速度分布和颗粒浓度分布性能试验表明，该系统对小颗粒具有良好的性能。
A low-cost wind tunnel for aerosol studies has been designed, constructed, and evaluated for aerosol uniformity with 2- and 0.46-µm particles. A commercial nebulizer was used to produce the suspended test particles, and a custom-made, four-hole injector was used to introduce the aerosol into the wind tunnel. A commercially available optical particle counter measured the particle concentration. Performance tests of the velocity profile and particle concentration distribution at two flow rates showed that the system performs well for small particles.
