Experimental Study on the Performance of Three Vertical Axis Hydrokinetic Turbines

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Vertical‐axis hydrokinetic turbines have shown remarkable potential as a renewable energy option. However, their hydrodynamic performance remains uncategorized under turbulent, sedimented river flow conditions. This study presents a thorough and systematic experimental investigation to understand the impact of induced flow dynamics on three primary ...

From Complexity to Efficiency: Sensitivity‐Based Parameter Reduction in OWC Turbine Optimization

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
This work presents a multiparametric optimization of a counter‐rotating axial impulse turbine for oscillating water column (OWC) devices. Given the high computational cost required for optimizing numerous geometric parameters, a sensitivity analysis based on the Morris Method has been employed to reveal the most important ones prior to the optimization

CFD‐Based Hydrodynamic Performance Analysis of a Convex Overtopping Wave Energy Converter

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Overtopping wave energy converters (WECs) are increasingly recognized as high‐potential coastal energy harvesters, where hydrodynamic efficiency is intrinsically regulated by ramp geometry and nonlinear wave–structure interaction mechanisms. This study presents a numerical investigation of the hydrodynamic performance of a convex‐type overtopping ...

On the Development of a Near-Shore Pivoting Wave Energy Converter

Energies
Numerous offshore wave energy converter (WEC) designs have been invented; however, none has achieved full commercialization so far. The primary obstacle impeding WEC commercialization is the elevated levelized cost of energy (LCOE).
