Tidal turbine array optimisation using the adjoint approach

Funke, S.W.; Farrell, P.E.; Piggott, M.D. - In: Renewable Energy 63 (2014) C, pp. 658-673

Oceanic tides have the potential to yield a vast amount of renewable energy. Tidal stream generators are one of the key technologies for extracting and harnessing this potential. In order to extract an economically useful amount of power, hundreds of tidal turbines must typically be deployed in...

A Numerical Model of the Wave that Overtopped the Vajont Dam in 1963

Bosa, Silvia; Petti, Marco - In: Water Resources Management 27 (2013) 6, pp. 1763-1779

The Vajont landslide took place in northern Italy on October 9th 1963 and caused a huge impulse wave to travel along the artificial reservoir and overtop the dam, flooding and devastating a considerable area along the Piave riverbed. In this event about 1900 people died, 1700 of them in the...

Comparison of unstructured finite-volume morphodynamic models in contracting channel flows

Benkhaldoun, Fayssal; Daoudi, Salah; Elmahi, Imad; … - In: Mathematics and Computers in Simulation (MATCOM) 81 (2011) 10, pp. 2087-2097

Unstructured finite volume methods are receiving increased attention mainly because of their ability to provide a flexible spatial discretization. Hence, some areas can be resolved in great detail while not over-resolving other areas. Development of these models is an ongoing process with...

Boussinesq systems in two space dimensions over a variable bottom for the generation and propagation of tsunami waves

Mitsotakis, D.E. - In: Mathematics and Computers in Simulation (MATCOM) 80 (2009) 4, pp. 860-873

Considered here are Boussinesq systems of equations of surface water wave theory over a variable bottom. A simplified such Boussinesq system is derived and solved numerically by the standard Galerkin-finite element method. We study by numerical means the generation of tsunami waves due to bottom...
