COMPUTATIONAL FLUID DYNAMICS STUDY OF INCOMPLETE AIR MIXING IN A SLOT-VENTILATED ENCLOSURE, PART I: FLOW FIELD CHARACTERISTICS

Abstract

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.
