Natural laminar flow airfoils have achieved such a level of refinement that further
optimisation and subsequent wind tunnel testing need to regard the specific free-stream …

Wind tunnel investigations of how Natural Laminar Flow (NLF) airfoils respond to
atmospheric turbulence require the generation of turbulence, whose relevant characteristics …

Using flight measurements conducted between altitudes of 700 and 3000 m, this work
characterizes atmospheric turbulence and investigates the effects of an increase in …

Aircraft and wind turbines are two examples of machines for which viscous friction drag has
a profound influence on the performance. Consequently, the reduction of friction drag is an …

This thesis numerically investigates the laminar-to-turbulent transition in boundary-layer
flows on natural laminar flow airfoils under oscillating inflow conditions. Large-scale …

This paper introduces the Low Acoustic Noise and Turbulence (LANT) wind tunnel of the
Sao Carlos School of Engineering, University of Sao Paulo (USP-EESC), Brazil. The closed …

Direct numerical simulations (DNS) of laminar to turbulent transition in presence of free-
stream turbulence (FST) on a laminar flow airfoil are performed. The present article briefly …

The effect of inflow turbulence level on the boundary layer transition on a Natural Laminar
Flow (NLF) airfoil is investigated through detailed wind tunnel measurements. The free …
