Description:
Determination of indoor exposure levels commonly involves assumptions of fully mixed ventilation conditions. In the effort to determine contaminant levels with efficiency, the nodal approach is common in modeling of the indoor environment. To quantify the transport phenomenon or localized exposure and comfort levels another approach is required, commonly through the use of computational fluid dynamics (CFD). As with modeling, these tools require validation before a level of confidence can be placed on the results. Towards this goal, an experimental particle image velocimetry (PIV) database has been generated around a thermal, breathing, rotating manikin in a cubical setting. In addition, particle concentration and size information was acquired in the breathing zone to quantify the effects of rotational motion on particle entrainment, due to convection by the thermal plume.
