We examine the effect of varying roughness-element aspect ratio on the mean velocity
distributions of turbulent flow over arrays of rectangular-prism-shaped elements. Large-eddy …

Efficient tidal turbine designs rely upon the hydrodynamic performance of the turbine blade
sections. A significant consideration for the likely power generation capacity of a tidal turbine …

We conduct a series of large eddy simulations (LES) of turbulent boundary layers over
arrays of cuboidal roughness elements at arbitrary orientation angles (non-frontal …

The adverse effects of marine biofouling on marine renewable energy devices are well
established. In recent fundamental investigations on fluid flow over this type of surface …

Bio-fouling formation and growth can significantly alter the surfaces of most structures,
systems, or equipment designed to operate in the marine environment. Many effective anti …

In most fundamental studies on the effect of roughness elements on wall-bounded
turbulence regular arrangements of roughness elements are investigated. In this study …

The current drive to generate energy from sustainable renewable resources has led to an
increased interest in generating power through exploiting the kinetic energy in faster flowing …
