Comparison of turbulent boundary layers over smooth and rough surfaces up to high
Reynolds numbers Page 1 J. Fluid Mech. (2016), vol. 795, pp. 210–240. c Cambridge …

A great deal of effort has been expended in measuring turbulence phenomena in clean air
flows. However, no previous measurements have been successfully made of the vertical …

The effects of wall roughness on turbulence structure modifications were explored by
numerical experiments, carried out using Large Eddy Simulation techniques. The wall …

An analytical method is presented for determining the Reynolds shear stress profile in
steady, two-dimensional wall-bounded flows using the mean streamwise velocity. The …

Flow separation and vortex shedding are some of the most common phenomena
experienced by bluff bodies under relative motion with the surrounding medium. They often …

Turbulent flow in a channel with irregular two-dimensional rough surfaces is analysed
through wall-resolving large eddy simulation (LES). Both walls of the channel are …

The sinusoidal roughness effect is investigated using a direct numerical simulation (DNS) of
a spatially developing turbulent boundary layer (TBL) over three-dimensional sinusoidal …

Wall-resolved Large Eddy Simulation of fully developed turbulent channel flows over two
different rough surfaces is performed to investigate on the effects of irregular 2D and 3D …

An integral method to evaluate skin friction coefficient for turbulent boundary layer flow is
presented. The method replaces streamwise gradients with total stress gradients in the wall …

Motivated by the need for accurate determination of wall shear stress from profile
measurements in turbulent boundary layer flows, the total shear stress balance is analysed …
