Kurzfassung
Efficient removal of airborne pathogens is a key feature of ventilation concepts. A promising approach to control and prevent aerosol spreading in indoor environments is the air curtain, a planar turbulent jet that prevents air exchange between two volumes. Therefore, we investigate the interaction of aerosol particles of the size of typical human exhalation with the turbulent flow field of the air curtain. First, we evaluate the velocity field and the turbulence intensity distribution generated by the air curtain. Further, we investigate the resulting spatial aerosol particle concentration distribution for two different air curtain configurations. The effectiveness of both configurations against aerosol passage is evaluated using a particle-based air curtain effectiveness and shows local advantages of up to 13.5% for the higher flow rate.
