The quest for reductions in fuel consumption and CO 2 emissions in transport has been a
powerful driving force for scientific research into methods that might underpin drag-reducing …

Direct numerical simulations have been performed to study the effect of a stationary
distribution of spanwise wall-velocity that oscillates in the streamwise direction on a …

Spanwise wall oscillation is an easily implemented active control scheme. It can delay the
transition to turbulent flows in incompressible boundary layers under appropriate control …

Direct numerical simulations have been performed to study the effect of an oscillating
segment of the wall on a turbulent boundary layer flow. Two different oscillation amplitudes …

Direct numerical simulations (DNS) of Mach= 2.9 supersonic turbulent boundary layers with
