Renewable energy provides an effective solution to the problem existing between energy
and environmental protection. Tidal energy has great potential as a form of renewable …

Large-Eddy Simulations are reported, dealing with an axial-flow hydrokinetic turbine
operating in the wake of an upstream one. Computations were conducted on a cylindrical …

To optimise a tidal site for development, tidal stream turbines need to be placed within
arrays with the spacing between turbines being critical to maximise energy yield whilst …

Ocean energy extraction is on the rise. While tides are the most predictable amongst marine
renewable resources, turbulent and complex flows still challenge reliable tidal stream …

The climate crisis is driving policy makers, energy companies and chemical industries to
accelerate the transition from conventional high-carbon ammonia to low-carbon and zero …

To design tidal stream turbine arrays, turbine wakes need to be fully characterized to assess
the adequate row spacing considering environmental factors such as onset turbulence …

Tidal and wind energy projects almost exclusively adopt horizontal axis turbines (HATs) due
to their maturity. In contrast, vertical axis turbines (VATs) have received limited consideration …

When two horizontal rotors are put side-by-side, with slight gaps between them (less than
two diameters), the flow velocity near the centerline is higher than the free stream. In this …

Performance and wake interaction between two aligned vertical turbines are investigated by
solving the three-dimensional Navier-Stokes equations with the k− ω SST IDDES turbulence …

Tidal and riverine flows are viable energy sources for consistent energy production.
Installing and operating marine hydrokinetic (MHK) turbines requires assessing any …
