COMPUTATIONAL FLUID-DYNAMICS STUDY OF INCOMPLETE AIR MIXING IN A SLOT-VENTILATED ENCLOSURE .1. FLOW-FIELD CHARACTERISTICS

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