  5. 5. Mooring dynamics for wave energy applications

    Detta är en avhandling från Chalmers University of Technology

    Författare :Johannes Palm; Chalmers tekniska högskola.; Chalmers University of Technology.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hp adaptivity; Coupled simulations; Mooring dynamics; Wave energy; Snap loads; Discontinuous Galerkin methods; OpenFOAM; CFD; RANS;

    Sammanfattning : 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). LÄS MER
