摘要
In order to study the characteristics of wind turbine wake in typical complex terrains, a numerical model based on lattice Boltzmann method (LBM) and large eddy simulation (LES) was adopted. To verify the reliability of the calculation model, three sub-grid scale turbulence models were selected to simulate the flow field induced by the MEXICO wind turbine. It is found that the wall adaptive local eddy (WALE) model performs better than the others investigated. Then, the flow field of a 2 MW wind turbine on typical hills with different slopes was calculated and analyzed by using the WALE model. The results were compared with that in the flat terrain. It is found that the wind turbine wake at the top of the hill interacts with the backflow on the leeward side of the hill. The wakes of both wind turbine and hill on the leeward side are mixed with each other, and the wake of wind turbine will move downward along the slope of the hill when the slope is small. © 2020 Chin.
