Résumé

This article reports on the computed flaw characteristics of a slot-ventilated enclosure. The flow was mathematically modeled with an asymptotically consistent low-Reynolds-number k-ϵ model, A comparison of computed and experimental flows reveals that (1) 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-ϵ model demonstrates the need for developing damping functions that do not involve the nearest wall distance and the wall shear velocity.
