▪ Abstract This is a review of the mechanisms that control neutrally stable turbulent boundary-
layer flow over hills and waves, their relative magnitudes, and how they exert their greatest …

Abstract The Askervein Hill project was a collaborative study of boundary-layer flow over low
hills carried out under the auspices of the International Energy Agency Programme of R & D …

It is more than half a century since the publication of RA Bagnold's classic book The physics
of blown sand and desert dunes, and it is a tribute to the quality of Bagnold's work that many …

Research in wind engineering at the Building Research Establishment and elsewhere in the
world, together with the BRE survey of wind damage over the past two decades has led to a …

Untitled Page 1 Page 2 GEOMORPHOLOGY OF DESERT DUNES Sand dunes cover up to a
quarter of many desert regions. Determining the factors that determine their shape, size and …

We review developments in the field of boundary-layer flow over complex topography,
focussing on the period from 1970 to the present day. The review follows two parallel …

A general analysis is developed for turbulent shear flows over two‐and three‐dimensional
hills with low‐slopes which allows for a wide range of upwind velocity profiles, such as those …

Abstract Accurate and reliable Computational Fluid Dynamics (CFD) simulations of wind
flow over natural complex terrain are important for a wide range of applications including …

An investigation of the modification of airflow by a discrete, semi-circular roughness element
(in this case, vegetation), the resulting flow structure, and the formation of pyramidal-shaped …

Bolund measurements were used for a blind comparison of microscale flow models. Fifty-
seven models ranging from numerical to physical were used, including large-eddy …
