Numerical investigation of the aerodynamic characteristics on an open circuit tunnel

Numerical investigations were carried out to study the aerodynamic characteristics on an open circuit tunnel. The considered tunnel was designed and realized to develop experimental investigations of different wind turbines. In this study, we are interested to verify that the test vein provide a uniform out flow, a high-speed and a low-turbulence. The numerical model used is based on the resolution of the Navier-Stokes equations in conjunction with the standard k-ε turbulence model. These equations are solved by a finite volume discretization method. The numerical results from the application of the CFD code FloWorks are presented in the transversal and longitudinal planes of the wind tunnel. The comparison between the numerical results and the global experimental results, conducted within a hot wire anemometry AM-4204 model, confirm the validity of the numerical method.
