风力机尾流流场的数值分析和尾流边界建模
Numerical Analysis and Wake Boundary Modeling of Wind Turbine Flow Fields
摘要
Abstract
The development of the wake boundary after an actuator disc is simulated using the computa-tional fluid dynamics (CFD) method. To capture the details of wake boundary, the adaptive spring-mesh technique is used to make the finest meshes always follow the wake boundary movement, accord-ing to the fact that the velocity gradient in the wake boundary is much larger than in other regions. A wake boundary model has been developed based on the CFD results. This model divides the wake devel-opment into the expanding process due to inviscid flow and the diffusing process due to viscous influ-ence. The reliability of the model is validated by comparing with experimental data. As a demonstration of application, a newly developed wake velocity model called Gaussian distribution prediction (GDP) model is improved by the present wake boundary model.关键词
