Biological flows in swimming and flying bio-locomotion usually involve intricate flexible or
rigid structures that undergo large deformations and displacements, as well as rich …

The immersed boundary method is a methodology for dealing with boundary conditions at
fluid–fluid and fluid–solid interfaces. The immersed boundary method has been attracting …

In this paper we report on the design and testing of a novel vertical axis wind turbine (VAWT)
system. The system consists of two counter-rotating VAWT rotors and a deflector that is …

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 …

When dealing with multirotor devices such as quadcopters or wind farms, the cost of blade-
resolved large-eddy simulation (LES) becomes prohibitive. Combining LES with a family of …

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 …

Dependence of wake features of a Vertical Axis Wind Turbine (VAWT) on Tip Speed Ratio
(TSR) is studied in the present work, using a computational approach, based on Large-Eddy …

Vertical axis wind and tidal turbines are a promising technology, well suited to harness
kinetic energy from highly turbulent environments such as urban areas or rivers. The power …

The wake recovery downstream of a vertical axis turbine operating in a turbulent channel
flow is investigated via detailed velocity measurements using an Acoustic Doppler …

Abstract Design of efficient tidal arrays relies on the adopted spacing between turbines and
their mutual interplay. Turbines affected by wake shadowing operate in harsher flow …
