Within the scope of the research project, the effect of turbulence on the mixing and filtering of aerosol particles in rooms of different geometry will be systematically analyzed. The spatial and temporal scales of turbulence will be varied over a large range using turbulence generators in order to quantify the mixing processes of aerosol particles and to determine their separation efficiency. It is expected that the turbulent scales and the intensity of turbulence are important parameters responsible for reducing the viral load in rooms and thus determining the filter performance. The results of these experimental analyses will provide valuable insight into how indoor airflow must be conditioned to efficiently reduce indoor viral loads.

在研究项目范围内，将系统地分析湍流对不同几何形状房间内气溶胶颗粒混合和过滤的影响。湍流的空间和时间尺度将使用湍流发生器在很大范围内变化，以量化气溶胶颗粒的混合过程，并确定其分离效率。预计湍流尺度和湍流强度是负责降低室内病毒载量的重要参数，从而决定过滤器性能。这些实验分析的结果将为如何调节室内气流以有效降低室内病毒载量提供有价值的见解。
