Behaviour of eigenmodes of an array of oscillating water column devices

Advances and Challenges in Wave Energy Park Optimization—A Review

“…modes (De Chowdhury and Manasseh, 2017;Wolgamot et al, 2017), interaction distance cut-off (Göteman et al, 2015a), a nearest neighbor approach (Sarkar et al, 2016), and Haskind's relation (Flavià and Clément, 2017) have been introduced. Both the iterative and non-iterative versions of the multiple scattering theory have been further developed and used to model the hydrodynamics of wave energy parks (Ji et al, 2015;Konispoliatis and Mavrakos, 2016;Göteman, 2017;Ruiz et al, 2017;Fang et al, 2018;Giassi and Göteman, 2018;Zheng et al, 2018Zheng et al, , 2019Liu et al, 2019).…”

Floating Oscillating Water Column Wave Energy Converters: A Review of Developments

“…The conclusion was that the array spacing can significantly affect the total power output, especially when the inter-body distance in the array is close to the wavelength. In [158], the study examined the effect of inter-body spacing on the eigenfrequencies of an OWC array in an equilateral triangle. The findings indicated that the maximum power absorption might occur at a specific distance where the damping of the dominant eigenmode is less than that of a single converter.…”

Modelling and Optimisation of Wave Energy Converters

“…For instance, the analytical multiple scattering method was coupled to a numerical method to allow for arbitrary body geometry [530], and was further used to study wave farm interactions and the existence of trapped wave modes [245]. To reduce the computational cost and allow for the optimisation of large wave farms, methods using interaction distance cut-offs [300], nearest neighbor approaches [689], resonant modes [164,837], Haskind's relation [244], and multiple cluster scattering [299] have been introduced, connecting the iterative and non-iterative versions of multiple scattering.…”
