IMPACT OF LES TURBULENCE SUBGRID MODELS IN THE JET RELEASE SIMULATION

FERREIRA JÚNIOR, E. S.; VIANNA, S. S. V.

Artigo Completo:

The right choice of sub-grid scale (SGS) models in any simulation scenario plays an important role, since it can lead to more accurate results. This paper aims to investigate SGS models in order to perform jet release simulation accurately. Fire Dynamics Simulation (FDS) code is used for this propose. Preliminary results for jet centreline velocity profile are obtained considering four different SGS models. Findings are compared with analytical model. Three of four SGS models investigated let to excellent results.
