Measurement of two-dimensional air velocities in a full-scale room using particle image velocimetry (PIV).

Author(s) : ZHAO L., ZHANG Y., WANG X., et al.

Summary

The system configuration, instrumentation, equipment development, measurement capability and results are presented in the paper. The results show that the PIV technique can be an effective method to quantitatively measure the room air velocity, especially for those regions with very low velocity. The air velocity distribution measured using PIV can be used to analyse ventilation system performance and strategies. Even with slot inlet and slot outlet, the third-dimensional velocity component becomes substantial as the ventilation rate increases. It implies that three-dimensional velocity profiles are needed to develop CFD models.
