Over the last 50 years the large-eddy simulation (LES) technique has developed into one of
the most prominent numerical tools used to study transport processes in the atmospheric …

Large-eddy simulations (LES) are used to gain insight into the effects of trees on turbulence,
aerodynamic parameters, and momentum transfer rates characterizing the atmosphere …

The occurrence of secondary flows is investigated for three-dimensional sinusoidal
roughness where the wavelength and height of the roughness elements are systematically …

Turbulent flows over dense canopies consisting of rigid filaments of small size are
investigated using direct numerical simulations. The effect of the height and spacing of the …

Non-stationarity is the rule in the atmospheric boundary layer (ABL). Under such conditions,
the flow may experience departures from equilibrium with the underlying surface stress …

Dynamics and organized turbulence structure in the atmospheric boundary layer (ABL) over
a real urban area, Mong Kok neighborhood in Kowloon Peninsula, Hong Kong, is …

The mixing-layer analogy is due to Raupach, Finnigan & Brunet (Boundary-Layer Meteorol.,
vol. 25, 1996, pp. 351–382). In the analogy, the flow in the roughness sublayer of a …

Using analyses of data from extant direct numerical simulations and large-eddy simulations
of boundary-layer and channel flows over and within urban-type canopies, sectional drag …

We show that the mean wall-shear stresses in wall-modeled large-eddy simulations
(WMLES) of high-speed flows can be off by up to ≈ 100\%≈ 100% with respect to a DNS …

This article presents the evolutionary history of immersed boundary methods (IBMs), tracing
their origins to the very beginning of computational fluid dynamics in the late 1950s all the …
