Thesis Title

Towards the effectiveness of buoyancy-driven flow in mitigating indoor airborne disease transmission

Research overview

There are two types of ventilation: mixing ventilation and displacement ventilation. In displacement ventilation, the air is brought by cool air from the floor level, and the background warm air is removed from the top. This can be either achieved mechanically using fan/diffusers, or just by the fact that the warmer air tends to rise. In mixing ventilation, which is perhaps the most widely used ventilation system, the cold air is supplied from the top of the room and the goal is to have a well-mixed room. The question that remains at the core of scientific discussion is that which of these two types of ventilation is best for infection prevention? Research suggests that promoting stratification can potentially provide an improved indoor air quality for infection control and reduce the energy consumption. My research aims to assess the effectiveness of such buoyancy-driven ventilation flows by conducting experimental fluid dynamical modelling in real spaces.
