A theoretically based relationship for the Darcy–Weisbach friction factor for rough-bed open-
channel flows is derived and discussed. The derivation procedure is based on the double …

The dynamics of a cantilevered elastic sheet, with a uniform steady flow im**ing on its
clamped end, have been studied widely and provide insight into the stability of flags and …

A large-eddy simulation (LES) of a laboratory-scale horizontal axis tidal stream turbine
operating over an irregular bathymetry in the form of dunes is performed. The Reynolds …

The efficiency of tidal stream turbines in a large array depends on the balance between
negative effects of turbine-wake interactions and positive effects of bypass-flow acceleration …

Until recently tidal stream turbine design has been carried out mainly by experimental
prototype testing aiming at maximum turbine efficiency. The harsh and highly turbulent …

Vertical axis tidal turbines (VATTs) are perceived to be an attractive alternative to their
horizontal axis counterparts in tidal streams due to their omni-directionality. The accurate …

Large-eddy simulations of turbulent flow in partially filled pipes are conducted to investigate
the effect of secondary currents on the friction factor, first-and second-order statistics and …

A three-dimensional Cartesian cut-cell method for the large-eddy simulation of two-phase
flows with moving bodies is presented in this study, which combines a volume-of-fluid …

Large-eddy simulations (LES) of the flow over a non-uniformly roughened channel bed are
carried out to study the effect of non-uniform bed roughness on turbulence driven secondary …

Eulerian-Lagrangian approaches capable of accurately reproducing complex fluid flows are
becoming more and more popular due to the increasing availability and capacity of High …
