This paper describes a study of changes in the vortex formation and the turbulent wake from
a circular cylinder with a finite aspect ratio, placed on a ground plane. The experiment was …

Lange bevor Leonardo da Vinci beobachtete, dass in einer Strömung die schlanken Körper
einen geringeren Widerstand aufweisen, als die stumpfen, hat die Menschheit von dieser …

In this study, wind flow is simulated via CFD over five 'nebkha'dune forms that range in
shape from a cone, to a hemisphere (approximately) and to a dome in order to examine the …

The near wake of a hemisphere immersed in a laminar boundary layer is studied utilizing
time-resolved tomographic particle image velocimetry (TPIV). Focus is placed on the three …

Five basic geometries (cylinder, cube, diamond, pyramid and hemisphere) are
comparatively examined at a Reynolds number of 1.7× 104 to determine the effect of a …

Although small‐scale spatial flow variability can affect both larger‐scale circulation patterns
and biological processes on coral reefs, there are few direct measurements of spatial flow …

Single-point turbulence statistics are compared in the roughness sublayer (RSL) of turbulent
open-channel flows over smooth wall and wall roughness with different textures using direct …

Field observations of scaled wind speed and sand transport recovery in the lee of a nebka
within a field of nebkhas and then subsequently for the nebkha denuded of its vegetation …

Supercritical turbulent boundary layer flow over a hemisphere with a rough surface (Re=
150000) has been simulated using Large Eddy Simulation (LES) and analyzed using the …

Obstacles in fluvial environments cause flow separation and the emergence of three-
dimensional flow fields that can lead to scour and deposition, even when no general …
