This study examined how the wake of a scaled turbine was changed by a bypass using
three different water depths with the hub at mid-depth, and one water depth with the hub at …

The Savonius hydrokinetic turbine is a viable alternative for rural electrification despite its
relatively low power coefficient. There are many ways to improve power performance …

Harnessing hydrokinetic energy from deep water to increase the operation periods of
observing platforms has received considerable attention in recent years. High-solidity …

The predictive capabilities of blade-resolved unsteady Reynolds averaged Navier-Stokes
(URANS) and detached eddy simulation (DES), the most commonly used hybrid RANS/large …

Tidal stream turbines (TST) deployed in open-water energetic sites are often unintentionally
at yaw to the incoming flow that causes performance degradation and deflection of the wake …

Turbulent non-homogenous flow environments at high-energy tidal sites lead to variation in
power performance of tidal stream turbines. In addition, non-uniform loading due to …

Social and political concerns on climate change have made renewable energy an essential
component of government's work plans. Grid-connected horizontal-axis hydrokinetic …

Study on the performance of the tidal stream turbines could greatly improve tidal stream
energy development. Up to date, few studies about the twin-rotor horizontal axis tidal …

Harnessing the power of tidal streams is a sustainable way of exploiting renewable marine
energy resources. It involves installing tidal stream turbines underwater to harness the …

The influence of the submergence depth ratio on the Savonius hydrokinetic turbine and flow
characteristics is numerically studied under different tip speed ratios. The tip speed ratio …
