摘要：

This article reports on the computed flow characteristics of a slot-ventilated enclosure. The flow was mathematically modeled with an asymptotically consistent low-Reynolds-number k-epsilon model. A comparison of computed and experimental flows reveals that (I) the airflow pattern of the experimental flow was reproduced by computed streamlines, and (2) computed velocity profiles were on average within -18% of those measured. Finally, an assessment of the proposed low-Reynolds-number k-epsilon model demonstrates the need for developing damping functions that do not involve the nearest wall distance and the wall shear velocity.
