Abstract
This study examines the way of utilizing a ceiling fan for airflow control in a large air-conditioned room. Although it seems that CFD simulation is useful in predicting the airflow around a ceiling fan, modeling of a ceiling fan as a rotating body is very complicated. Therefore, in this study, complex airflow of a ceiling fan is modeled as boundary conditions based on air velocity data near the ceiling fan obtained by the measurement. In this paper, the measured airflow pattern around the ceiling fan is compared with the CFD simulation result using the airflow model of the ceiling fan, in order to examine the validity of the airflow model. As a result, the CFD results were in good agreement with the measurement ones in respect of the average of air velocity.
