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

Direct numerical simulations were performed to investigate the behavior of laminar
separation bubbles subject to vertical gusts in an airfoil flow. Oscillating boundary-layer …

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 …

Linear stability analysis and wind tunnel measurements are performed to investigate the
behavior of laminar to turbulent transition in an oscillating airfoil boundary layer. A varying …

Direct numerical simulations (DNS) of bypass transition of a flat-plate boundary-layer subject
to free-stream turbulence (FST) were performed. A synthetic turbulent inflow is generated by …
