Abstract

Abstract To study airborne transport of aerosol particles by mixed convection and dynamic situations within a closed room, the Cottbus Aerosol Particle Reference Experiment (CARE) was built and equipped, which includes thermal manikins and a spreader dummy. For various flow configurations (location of spreader, heating bodies, windows opened, air ventilation with and without air purification systems) flow visualisation was performed, particulate matter sensors (PMS) measured local particle concentrations, head-mounted camera systems counted particle concentrations of individuals and finally, large field of view Shake-The-Box Particle Tracking delivered velocity fields. The comprehensive experimental configuration of different measurement systems are discussed in terms of their aerosol transport properties and quantitative results, effective application and comparative efficiency explaining the flow dynamics. The findings from these experiments also provide information under which circumstances particularly high concentrations of aerosol particles can be found on which locations.

动态情况下气溶胶粒子输运的参考实验

摘要为了研究密闭室内气溶胶颗粒在混合对流和动态情况下的空气传输，建立并配备了Cottbus气溶胶颗粒参考实验(CARE)，该实验包括热人体模型和扩散假人。对于各种流动配置(散布器的位置、加热体、打开的窗户、有或没有空气净化系统的空气通风)，进行了流动可视化，颗粒物质传感器(PMS)测量了局部颗粒浓度，头戴式摄像机系统计算了个体的颗粒浓度，最后，大视野的摇盒颗粒跟踪提供了速度场。从气溶胶输运特性和定量结果、有效应用和解释流动动力学的比较效率等方面讨论了不同测量系统的综合实验配置。这些实验的结果还提供了在何种情况下在何种地点可以发现特别高浓度的气溶胶颗粒的信息。
