Room ventilation and air purification became a hot topic in recent years due to the COVID-19 pandemic. Air purifiers can remove small particles and kill airborne viruses and bacteria, significantly improving the air quality within environments with poor ventilation.
Portable devices, however, tend to have a localised effect in a room, with some regions highly affected by its forced ventilation while others remain with stagnant and poorer quality air.
Within this study, we used passive scalars to track the concentration of purified air in the room. The model allowed us to evaluate the air quality uniformity within the space and highlight areas of poor circulation. We were also able to evaluate the sensitivities to the device operating conditions and to other external factors.
Two animations illustrate the approach taken. Video 1 shows the fraction of purified air in the room over time, while Video 2 shows the opposite, the fraction of unpurified air and is more suitable for visualising the areas with poorer flow quality.
This case study highlights an application with a relatively simple modelling approach, but which provided a valuable insight into the background application.
