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 …

Reducing turbulent skin friction drag is a fundamental goal for aircraft transportation to
conserve energy and decrease emissions. We introduce an annular dielectric barrier …

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 …

We present an experimental study of a turbulent boundary layer (TBL) control on a flat plate
using plasma actuators. Three different configurations of the actuators produce spanwise …

In this paper, surface-mounted arrays of pulsed-DC dielectric barrier discharge plasma
actuators are used to achieve skin friction drag reduction in turbulent boundary layers. The …

Experiments were performed using an active flow control approach that has shown the
ability to significantly reduce the viscous drag in turbulent boundary layers. The purpose of …

Drag control using a newly developed spanwise opposed wall-jet forcing (SOJF) method is
studied via direct numerical simulation of the incompressible Navier–Stokes equations in a …

The effect of Reynolds number (Re τ) on drag reduction using spanwise wall oscillation is
studied through direct numerical simulation of incompressible turbulent channel flows with …

THE inherent rise of friction drag above the laminar value in broad regions of turbulent flow
on aircraft surfaces distinctively deteriorates efficiency of airliners [1]. Research on turbulent …

Spanwise wall oscillation has been extensively studied to explore possible drag control
methods, mechanisms and efficacy–particularly for incompressible flows. We performed …
