Interest in the advancement of hydrokinetic energy conversion (HEC) technology has grown
substantially in recent years. The hydrokinetic industry has advanced beyond the initial …

A considerable body of research is currently being performed to quantify available tidal
energy resources and to develop efficient devices with which to harness them. This work is …

Marine hydrokinetic turbine, when operating in a shallow channel is subjected to the
boundary proximity effects from a deformable free surface on top and the channel bottom. A …

It is well known that a wake will develop downstream of a tidal stream turbine owing to
extraction of axial momentum across the rotor plane. To select a suitable layout for an array …

This paper reviews key issues in the physical and numerical modelling of marine renewable
energy systems, including wave energy devices, current turbines, and offshore wind …

The hydrokinetic industry has advanced beyond its initial testing phase with full-scale
projects being introduced, constructed and tested globally. However primary hurdles such …

Previous results from one-dimensional model studies have demonstrated that large-scale
exploitation of the tidal stream resource could have a significant impact on large-scale …

A strong contender for the utilization of the hydropower sources is Savonius turbine because
of its good starting characteristics and simplicity in fabrication. The aim of the present work is …

A new theoretical model is proposed to explore the efficiency of a long array of tidal turbines
partially blocking a wide channel cross-section. An idea of scale separation is introduced …

The Betz limit sets a theoretical upper limit for the power production by turbines expressed
as a maximum power coefficient of 16/27. While power production by wind turbines falls …
