Research of semi-empirical wind turbine wake models

For the purpose of exploring the wind turbine wake model of semi-empirical formula which based on the potential flow theory, the inviscid near-field wake model and two far-field wake model, the Jensen model and the improved Jensen model. Contraposing the shortage of the two Jensen models, physical amendments have been proposed, and the improved far-field wake models are obtained, then combined with the inviscid near-field wake model, two audience wake models are established, and compared them with the wind flow field measured data and other model results respectively. The results showed that the amendments proposed to the two Jensen models correspond with realistic flow field characteristics, the two established audience wake models of simple structure, the velocity calculation results agree with measured data, better than the commonly used Jensen model and improved Jensen model.
