Abstract

Wind turbines are highly complex structures for numerical flow simulation. Today, developments and increasing use of wind energy in the world has created a demand for progressively more accurate and efficient models for wind applications. Wind turbine wakes have significant effects on decreasing the produced power and blades fatigue loads, thus, the study on wake turbulence has great importance in wind turbine simulations. Actuator line model (ALM) is one of the most accurate models for characterization of the flow field and the turbulent wakes created by the turbines. AL model does not require boundary layer resolution and is therefore significantly more efficient than the fully-resolved computations. This model can accurately simulate the wakes of wind turbines operating in a flow field without any need to create or import the CAD turbine models and just by using turbine parameters. In this paper, AL method is implemented in openFOAM solver and a new method is used to spread forces on actuator lines. In order to validate the results, MEXICO rotor was modeled and large eddy simulation’s turbulence model is used to investigate the flow field around wind turbine. Simulation has been done for two different conditions including design conditions and stalled conditions. Results obtained for predicted wakes and performance parameters were compared to experimental data and it was observed that the ALM results agree well with measured data. Stall condition’s results were in better agreement with experimental data so that the thrust had 8.5% difference while torque and power showed difference of 2.8 and 2.4% respectively.
