Abstract

The normalization phase of the Covid-19 epidemic and numerous confirmed cases suggest it is necessary to develop effective control measures to mitigate airborne transmission. In this work, personalized air curtain (PAC)-personalized exhaust (PE) was proposed to reduce the inhalation of airborne aerosols in close proximity using a validated CFD model. Airborne aerosols were released from the infected person (IP) to simulate talking activities. PAC was installed between the healthy person (HP) and IP. PE was located above the PAC in order to exhaust the upward airborne aerosols immediately. Reduction of the HP's exposure caused by PAC-PV was up to 86% at a flow rate of 9 L/s. PAC-PE can further achieve a better performance than that of PAC alone (i.e. 73%). Results suggest that PAC-PE as a advanced ventilation strategy can be an effective control strategy and contribute to the mitigation of the spread of airborne transmission in indoor environments.
