Abstract
Open jet wind tunnel testing provides an alternative solution to expensive online wind power
measurements for researchers and small wind turbine developers. However, there is a lack of knowledge
for high Reynolds number and large diameter jet flows. In this paper, the structure of circular open jet
flows is reviewed. Theories and experimental correlations are combined to extend our understanding of
fully developed turbulent jets. Analytical relations are derived to calculate the correct wind power of the
jets. The corresponding reduction in power generated by small wind turbines is explained. The effects of
various parameters on the power production of a small wind turbine, such as the jet diameter, the distance
of the wind turbine from the jet nozzle and the wind turbine hub diameter, are investigated and the results
are discussed.
