AbstractExperiments were conducted in a full-scale text room (18 by 24 by 8ft [5.5 by 7.3 by 2.4 ml) for both isothermal and nonlsothermal conditions. Based on the experimental data, this paper discusses (1) the statistical features of air velocity fluctuations Including probability density functions and energy spectra; (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 1M 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. The detailed experimental data are also useful for evaluating and improving numerical simulation models of room air motion.
