Abstract

The validation and development of turbulence models are still important issues related to Computational fluid Dynamics for ventilation purpose.The present work continues the work initiated by (Voigt, 2002). Four turbulence models are reviewed, the k-e model, the k-w model and two blending models combining the k-e and the k-w model.The reason for testing the blending models is that the k-e model is the most robust, while the k-w model gives a better prediction of the size of the recirculation zone occurring in the Annex 20 rooms, see (Voigt, 2002). It is found that the blending function responsible for changing from the k-w model to the k-e model throughout the boundary layer does not work when simulating the flow in the Annex 20 test case. We analyze the topologies of the numerical flow fields and show that they agree with experiments as precisely as can be expected from a 2D simulation.
