The flow interaction of air distribution with thermal plumes and the effect on the air velocity fluctuation under increased heat load conditions

Flow interaction between thermal plumes and vertical air distribution and the resulting airflow structures were investigated under increasing heat load conditions. The main objective was to investigate the large-scale flow patterns, airflow fluctuation and frequency of the flow field. The flow interaction between thermal plumes and ventilation provides random flow motion and vortical structures that further effect the airflow characteristics such as velocity and temperature fields, turbulence intensity and frequency of the fluctuations.
