Surface roughness can significantly influence the fluid dynamics and heat transfer in
convective flows by inducing perturbations in the velocity profile which affect surface drag …

Turbulent flows are characterized by the non-linear cascades of energy and other inviscid
invariants across a huge range of scales, from where they are injected to where they are …

Large-eddy simulation (LES) has proven to be a computationally tractable approach to
simulate unsteady turbulent flows. However, prohibitive resolution requirements induced by …

The paper provides a brief introduction to the near-wall problem of LES and how it can be
solved through modeling of the near-wall turbulence. The distinctions and key differences …

Although the atmospheric sciences community has been studying the effects of atmospheric
stability and surface roughness on the planetary boundary layer for some time, their effects …

The hybridization of Reynolds-averaged Navier-Stokes (RANS) and large eddy simulation
(LES) methods is seen to be the most promising way to efficiently deal with separated …

This paper addresses one of the most persistent errors in wall-modeled large eddy
simulation: the inevitable presence of numerical and subgrid modeling errors in the first few …

We perform large-eddy simulation (LES) of a moderately convective atmospheric boundary
layer (ABL) using a prognostic subfilter-scale (SFS) model obtained by truncating the full …

The Effect of Mesh Resolution on Convective Boundary Layer Statistics and Structures Generated
by Large-Eddy Simulation in: Journal of the Atmospheric Sciences Volume 68 Issue 10 (2011) …

This paper solves an approximate form of conservation of mass and momentum for a turbine
in a wind farm array. The solution is a fairly simple explicit relationship that predicts the …
