Effect of the turbulence model on the heat ventilation analysis in a box prototype

Résumé

Investigations of the flow in a building system are crucial for understanding the fundamental basis of the aerodynamic structure characteristics. The CFD simulations were conducted using ANSYS Fluent 17.0 software, which solves the Navier-Stokes equations in conjunction with different turbulence models and by a finite volume discretization method. Particularly, a comparison between the experimental and standard k-, BSL k-, SST k-, standard k-, RNG k- and Realizable k- turbulence model has been developed. The comparison between the founded results affirms that the standard k- turbulence model is the most efficient to model the air flow in the present application. Indeed, the numerical results compared using the experimental data developed in the LASEM laboratory confirms the validity of the numerical method. The good agreements validate the considered computational method.
