ABSTRACT
The COVID-19 which is a respiratory disease spread by a virus of the coronavirus family has become a big problem leading to the closure of all academic as well as economic activities due to its capability to spread fast. In this study, we have investigated the effect to mix a disinfectant in aerosol form with air coming out from the air conditioning machine so it can reach all parts of the room to remove the virus and prevent the closure of certain necessary teaching–learning activities in the classroom. For this, the k-ε model which consists of two equations is used to numerically model the turbulent flow in the classroom. From the analysis, it can be found that high turbulent zones are formed in the room which can be an effective way of distributing the aerosol-based disinfectant in the classroom and from the particle tracker we can see the aerosol-based disinfectant reaching every corner. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
