Effect of Indoor Heat Intensity on Thermal Environment in High-rise Residential Building with Atrium
In this paper, model experiment and computational fluid dynamics (CFD) methods are adopted to study the effect of indoor heat intensity on thermal environment in high-rise residential building with atrium. The reduce-scale model of 1/25 is established by the similarity criterion mainly with Archimedes number so that it can reproduce the processes of ventilation and heat transfer effectively. Airflow in atrium sometimes becomes pseudo-laminar due to the damping effect. Therefore, the Reynolds Stress Model (RSM) is used to enhance the precision in CFD. Results of experiment and CFD agree with each other well. As a result, indoor heat intensity influences on temperature and airflow rate evidently, which presents a positive correlation relation with them. Also, it shows that the temperature-rise rate accelerates with the indoor heat source intensity enhancing through fitting the results of indoor temperature-rise. Thus, the indoor thermal environment of upper level is affected by indoor heat intensity most obviously, which causes uncomfortable feeling easily.
