Abstract

The current experimental investigation is focused on particle measurements using phase Doppler anemometry (PDA) in the breathing zone of a seated, breathing, thermal manikin under stationary and rotational conditions. Particle size, concentration, flux, and velocity data were collected both at the chamber inlet and in the manikin's breathing zone throughout the breathing cycle. In addition, simple oscillatory motion was added through manikin rotation to determine the impact on particle transport. The application of such experimental equipment to aerosols in the indoor environment provides the opportunity to assess the capacity of the human thermal plume to act as a transport mechanism to carry particulate matter (PM) into the breathing zone.
