Modeling Indoor Bioaerosols Dispersion Pattern Using the First Principle: A Case Study of One Bedroom Apartment

Abstract

Indoor bioaerosols dispersion within a building depends on certain conditions that make the apartment experience various deposition patterns. This challenge makes bioaerosols monitoring a very difficult exercise. In this study, mathematical experimentation was carried out in a one-bedroom apartment to investigate bioaerosols dispersion patterns in each compartment of the building. It was discovered that if the building is well ventilated either by the switching-on of a fan or air conditioner, turbulence dispersion would be observed in one of the compartments of the building and may lead to prolonged suspension of particulates within the building. Hence, bioaerosols retention in the building depends on the magnitude of the first-order rate constant for emission.
