Modelos de Turbulencia y su Implementación en el Código de Elementos Finitos Fantom

Marcela B. Goldschmit, Miguel A. Cavaliere

Abstract


In the present paper we analyze turbulence models for incompressible flow and we applied the finite element method of three models: the 1 model (where l is Prandtl's mixing length), the k - ε model (donde k is the turbulent kinetic energy) and the k-ε model (where ε is the turbulent energy dissipation rate). We use our (k - ε)-predictor / (ε)-corrector iterative scheme to overcome the numerical difficulties of k - ε model. We analyze computational results for a variety of turbulence flow problems.
