Full-scale experimental results on the mean and turbulent behaviour of room ventilation flows.

Author(s) : ZHANG J. S., WU G. J., CHRISTIANSON L. L.

Summary

Experiments were conducted in a full-scale test room for both isothermal and nonisothermal conditions. Based on the experimental data, the paper discusses: 1) the statistical features of air velocity fluctuations; 2) the observed airflow patterns; and 3) the spatial distributions of mean velocity, turbulence intensity, kinetic energy of turbulence, and mean temperature. Special attention is paid to the effects of the diffuser air velocities and internal heat loads on the flow characteristics and to the differences between the diffuser jet region and the occupied region.
