  2. 1. Mooring dynamics for wave energy applications

    Author : Johannes Palm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hp adaptivity; Wave energy; Coupled simulations; CFD; Discontinuous Galerkin methods; OpenFOAM; Mooring dynamics; Snap loads; RANS;

    Abstract : This work aims to increase the modelling accuracy of two important problems for the wave energy industry. One concerns the mooring dynamics in the presence of snap loads (shock waves in cable tension). The other is related to nonlinear effects in the resonance region of moored wave energy converters (WECs). READ MORE
