Journal ArticleDOI
Effects of frontal and plan solidities on aerodynamic parameters and the roughness sublayer in turbulent boundary layers
TL;DR: In this paper, the effect of surface morphology on the depth of the roughness sublayer (RSL) was investigated, and the results indicated that the RSL reaches a peak value λF ≈ 0.21 for a constant λP = 0.27.
Journal ArticleDOI
The energy cascade in near-field non-homogeneous non-isotropic turbulence
TL;DR: In this paper, particle image velocimetry (PIV) measurements of various terms of the nonhomogeneous Karman-Howarth-Monin equation in the most inhomogeneous and anisotropic region of grid-generated turbulence, the production region which lies between the grid and the peak of turbulence intensity.
Journal ArticleDOI
Evolution of the velocity-gradient tensor in a spatially developing turbulent flow
TL;DR: In this paper, an experimental study of turbulence generated by a low-blockage space-filling fractal square grid was performed using cinematographic stereoscopic particle image velocimetry in a water tunnel.
Journal ArticleDOI
A comparative study of the velocity and vorticity structure in pipes and boundary layers at friction Reynolds numbers up to 10(4)

TL;DR: In this article, Kwon et al. measured the full velocity and vorticity vectors in both pipe and boundary layer flows under matched spatial resolution and Reynolds number conditions, and found significant differences in the two transverse Reynolds normal stresses throughout the log layer and wake layer at Reynolds numbers.
Turbulent boundary layers developing over rough surfaces: From the laboratory to full-scale systems
TL;DR: In this paper, an overview of recent work on the problem of turbulent boundary layers developing over surface roughness is given, including experimental laboratory studies, numerical simu lations and recent attempts at full-scale in-situ measurements on the hull of an operating ship.
