An adaptive and energy-maximizing control of wave energy converters using extremum-seeking approach
Luca Parrinello, Panagiotis Dafnakis, Giovanni Bracco +3
In this paper, we systematically investigate the feasibility of different extremum-seeking (ES) control schemes to improve the conversion efficiency of wave energy converters (WECs…

Comparison of wave-structure interaction dynamics of a submerged cylindrical point absorber with three degrees of freedom using potential flow and computational fluid dynamics models
Panagiotis Dafnakis, Amneet Pal Singh Bhalla, Sergej Antonello Sirigu +3
In this paper we compare the heave, surge, and pitch dynamics of a submerged cylindrical point absorber, simulated using potential flow and fully-resolved computational fluid dynam…

Simulating water-entry/exit problems using Eulerian-Lagrangian and fully-Eulerian fictitious domain methods within the open-source IBAMR library
Amneet Pal Singh Bhalla, Nishant Nangia, Panagiotis Dafnakis +2
In this paper we employ two implementations of the fictitious domain (FD) method to simulate water-entry and water-exit problems and demonstrate their ability to simulate practical…
