Abstract
In this paper, wind tunnel tests of a scaled wind turbine have been performed to investigate the effects of turbulent intensity of oncoming flow on turbine wake field. The scaled turbine model was carefully designed to satisfy the similarity conditions. The wind velocities and turbulent intensities were measured using hotwire anemometer in order to compare with existing wake model. It was found from the tests that the existing wake models well fit with test results at turbulent flow rather than at uniform flow. Finally modified wake model has been proposed based on the measured data.
