Summary

Flow and temperature distributions in an atrium with a large ceiling height (130 m) are analyzed by means of computational fluid dynamics (CFD) and radiation simulation. The occupied region (the space near the floor) of the atrium, which is open to a large void space, is partially air conditioned. The effects of the flow and temperature fields of the void space on the occupied region are analyzed in detail. Then the effects of ventilation in the upper space of the atrium on the temperature distribution are examined. The analysis includes solar radiation (shortwave) simulation, radiative heat transfer (infrared) simulation, heat conduction simulation, and airflow and temperature distribution analysis of the atrium space (CFD analysis).
