工业散料转运和搬运过程中经常产生大量粉尘排放，严重威胁工人的身体健康。粉尘的分散和除尘通风都与颗粒流降过程中夹带的气流场有关。PIV测试系统用于测试颗粒自由流动和贴壁落壁过程中的夹带气流场。颗粒流自由落体过程：夹带气流速度在不同高度段呈高斯分布。颗粒主要沿宽度方向(d)扩散，沿长度方向(l)扩散不明显。颗粒流附着壁面下降过程：当/d≤5时，垂直壁面的存在对夹带空气流场有显著影响，夹带空气能更好地附着在垂直壁面上。当/d>5时，垂直壁面的存在对夹带气流流场影响不大，夹带气流基本与垂直壁面分离。该研究为工业颗粒输送系统的通风设计提供了理论依据
Industrial bulk material transfer and handling processes often result in large dust emissions and seriously threaten workers' health. Both dust dispersion and ventilation for dust removal are related to the entrained air flow field under the particle flow fall process. The PIV test system is used to test the entrained air flow field during the particle flow free and adheres wall fall process. The particle flow free fall process: The entrained air velocity show a Gaussian distribution at the different height sections. The particle diffuses mainly along the width-side(d), and the diffusion phenomenon is not obvious in the length-side(l) direction. The particle flow adheres wall fall process: Whens/d≤ 5, the existence of the vertical wall has a significant effect on the entrained air flow field, and the entrained air can better adhere to the vertical wall. Whens/d>5, the existence of the vertical wall has a little effect on the entrained air flow field, and the entrained air is basically separated from the vertical wall. This study provides a theoretical basis for the ventilation design of industrial particulate transport systems
