Numerical simulation of wind farm flow field

Abstract

Because of its high accuracy can be achieved and can reduce the gold investment, CFD calculations are widely used in wind farm construction projects. This paper uses the solver buoyantBoussinesqSimpleFoam of the open CFD software-OpenFOAM to simulate the wind farm. First, we use the flat terrain and homogeneous Atmospheric Boundary Layer (ABL) flow, corresponding to the atmospheric boundary layer of a neutral state, stable state and unstable state was established three groups of numerical simulation models to correctness of the models. The results show that the three models used in this paper have ideal simulation results for the atmospheric boundary layer, and can accurately calculate the atmospheric boundary layer containing temperature and buoyancy effects. By comparing the calculation results of Askervein Moutain and Bolund Island with the experimental data, it is found that: The calculation model and solver used in this paper can better calculate the wind resource distribution under complex terrain conditions, and the calculation results are accurate, which is in good agreement with the experimental values.
