Describes the application of particle image velocimetry (PIV) to the large-scale flow fields in the vicinity of a person in a room. Due to the large imaging areas required for such measurements (over two meters in each dimension) and the low air velocities (0.05 m/s), the PIV technique for this application encounters unique challenges including uneven illumination, large relative velocity errors, and large out-of-plane displacements within the thick light sheet. Intended that the experimental air velocity data describing the interaction between the human body and the room airflow is used for validation of CFD models for room airflow predictions.
