Investigation of human breathing aerosol transport

Human exhaled aerosol is an important transmission method of infectious diseases in indoor conditions. Hence, fluid mechanics and dispersion of such exhaled aerosol during breathing are important for indoor design and ventilation systems. In addition to sedentary conditions, the flow and expelled aerosols increase in heavier breathing rate scenarios like exercise, dancing, etc. The interest is to study the trajectory of the puff from breathing and the resulting dispersion of the expelled aerosols.

In this regard, the project is aimed to utilize a human-like breathing system and develop methods to obtain particle concentration measurement from optical data in addition to particle image velocimetry for velocity field determination.
