An experimental investigation of how human activities affect the behaviour of indoor airborne particles

The outbreak of COVID-19 in 2019 triggered soaring public concern about respiratory infectious diseases. The motion of virus-carrier particles has also been researched by academia due to its susceptible characteristics caused by various factors. Particle behaviours can be influenced by human activities inducing effects, which can be regarded as an opportunity to support the development of efficient strategies for coping with infectious diseases. By performing simulation experiments, this paper investigated how door opening and human walking influence the behaviour of indoor PM0.5 and PM2.5. The results show that better understanding the effect of human activities may help control virus-carrying particles indoors
