THE FORMATION OF WIND PROFILE IN ENVIRONMENT SIMULATION LABORATORY

The numerical simulation and the experimental test are used to investigate the formation of the wind profile of the neutral atmospheric surface layer by screens in the environment simulation laboratory. Taking the screen layout program with variations of porosity of screens as a guide, 30 meshes and 16 meshes with fixed porosity of screens with respective heights of four screen layer collocations are selected. The complex screens are simplified as the porous media model and the k-εvarepsilon model in using the software Fluent. The results show that the screens can be simulated with the porous media and the wind profile can be formed by the compounding of fixed porosity screens in a short experimental section. The simulation results agree well with those of experiment.
