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 …

Computational fluid dynamics models based on Reynolds-averaged Navier–Stokes
equations with turbulence closures still play important roles in engineering design and …

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 …

Xcompact3D is a Fortran 90–95 open-source framework designed for fast and accurate
simulations of turbulent flows, targeting CPU-based supercomputers. It is an evolution of the …

Direct numerical simulations of compressible turbulent channel flows are performed for bulk
Mach numbers 0.8 and 1.5 and bulk Reynolds numbers in the range of 3000–34 000. The …

Large-eddy simulations of turbulent flow in partially filled pipes are conducted to investigate
the effect of secondary currents on the friction factor, first-and second-order statistics and …

We report on an experimental investigation on the effect of sinusoidal riblets on the near-
wall characteristics of a turbulent boundary layer. The investigated riblets are characterized …

Well-resolved direct numerical simulations (DNS) have been performed of the flow in a
smooth circular pipe of radius dependence at an intermediate distance from the wall–also …

A growing body of studies in wall-bounded turbulence has shown that the generation of wall-
shear stress fluctuations is directly connected with outer-layer large-scale motions. In the …
