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 …

Transient growth and resolvent analyses are routinely used to assess nonasymptotic
properties of fluid flows. In particular, resolvent analysis can be interpreted as a special case …

This book is a comprehensive and intensive monograph for scientists, engineers and
applied mathematicians, as well as graduate students in fluid dynamics. It starts with a brief …

A 50 year journey through flow control strategies that seek to achieve viscous drag reduction
in turbulent boundary layers is presented. These are shown to focus on different …

The development of the One Atmosphere Uniform Glow Discharge Plasma has made it
possible to cover the wings and fuselage of aircraft with a thin layer of glow discharge …

Direct numerical simulations of the incompressible Navier–Stokes equations are employed
to study the turbulent wall-shear stress in a turbulent channel flow forced by lateral …

▪ Abstract Drag reduction in wall-bounded flows can be achieved by transverse motions
imposed by passive means, eg, riblets, or by external forcing, such as wall oscillation or …

Computational experiments based on direct numerical simulation of wall-bounded flow
reveal that turbulence production can be suppressed by the action of a transverse travelling …

Direct numerical simulations for fully developed channel flow, subjected to oscillatory
spanwise wall motion, have been performed and analysed in an effort to illuminate the …

DNS results for turbulent channel flow with two-and three-dimensional roughness elements
are discussed. The focus is on surfaces where the separation between consecutive …
