Analysis of Dispersion and Prediction of Infection Possibility according to Airborne Viral Contaminants: Tracer gas simulation

摘要

The aim of this study is to analyse the physical characteristics of airborne virus, consider the possibility of using coupled analysis model and tracer gas for analysing virus diffusion in building space and, based on reports of how the infection spread in a hospital where patients were discovered, analyse infection risk using tracer gas density and also diffusion patterns according to the location, shape, and volume of supply diffusers and exhaust grilles. This paper can provide standards and logical principles for evaluating various alternatives for making decisions on vertical or horizontal ward placement, air supply and exhaust installation and air volumes in medium or high story medical facilities.
