Abstract

A finite volume renormalization group (RNG) k-ε turbulent model was employed to simulate an under-floor air distribution (UFAD) system consisting of eight swirl diffusers. Mesh generation was conducted using PRO/E and GAMBIT . Computational fluid dynamics (CFD) results using FLUENT show both flow and thermal patterns for an instrumented laboratory room (Building Technology Laboratory-BTL) located at the University of Nevada Las Vegas. Simulation results are presented using symmetrical boundary settings for the BTL. Stratification heights and clear zones are discussed. The application of CFD simulation provides insightful analyses in UFAD design and placement.
