In this work the effect of LEBUs as passive method for the heat transfer control of turbulent boundary layers is investigated. Different LEBU configurations, with and without vortex generators, have been tested to analyse their effect on the convective heat transfer coefficient in a moderate friction-based Reynolds number turbulent boundary layer. Heat transfer measurements with infrared thermography are performed in order to estimate the wall convective heat transfer coefficient fluctuations.
