Laminar to Turbulent Transition at Unsteady Inflow Conditions: Direct Numerical Simulations with Small Scale Free-Stream Turbulence
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 explains theExpand
Laminar to Turbulent Transition due to unsteady Inflow Conditions: Wind Tunnel Experiments at increased Turbulence Levels
Within the Luftfahrtforschungsprogramm (LuFo), measurements on a laminar flow airfoil in flight as well as in a wind tunnel are combined with direct numerical simulations (DNS) to provide the baseExpand
Laminar to Turbulent Transition at Unsteady Inflow Conditions: Wind Tunnel Measurements at Oscillating Inflow Angle
Wind tunnel measurements have been performed to investigate the effect of large scale turbulence on the laminar to turbulent transition on a natural laminar flow airfoil through cyclic 2D variationsExpand
