Effects of blade load distributions on wind turbine wake evolution using a blade resolved CFD simulations

摘要

An analysis of a pair of small-scale turbines designed using blade element momentum theory is performed using blade-resolved numerical simulation. Analysis on the wake structures are studied using Reynolds stress analysis to compare the differences due to differing blade load distribution. The results show that relatively small differences in blade loading can lead to significant differences in wake structures which persist far downstream. This implies that extreme care should be taken to match experimental blade loading with industrial scale turbine loading.
