  2. 1. Extreme wave conditions and the impact on wave energy converters

    Author : Eirini Katsidoniotaki; Malin Göteman; Vincent Neary; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extreme waves; wave energy converters; CFD; OpenFOAM; environmental contours; focused waves; breaking waves;

    Abstract : The amount of energy enclosed in ocean waves has been classified as one of the most promising renewable energy sources. Nowadays, different wave energy conversion (WEC) systems are being investigated, but only a few concepts have been operated in a sea environment. READ MORE

  4. 2. 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

  5. 3. Wave Loads and Peak Forces on Moored Wave Energy Devices in Tsunamis and Extreme Waves

    Author : Linnea Sjökvist; Malin Göteman; Mats Leijon; Peter Stansby; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OpenFOAM; CFD; Wave power; Tsunami waves; Extreme waves; Offshore; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Surface gravity waves carry enormous amounts of energy over our oceans, and if their energy could be harvested to generate electricity, it could make a significant contribution to the worlds power demand. But the survivability of wave energy devices in harsh operating conditions has proven challenging, and for wave energy to be a possibility, peak forces during storms and extreme waves must be studied and the devices behaviour understood.

  6. 4. Combustion characteristics of some alternative fuels in ICE: : a detailed numerical study

    Author : Siyuan Hu; Strömningsteknik; []
    Keywords : Combustion; duel fuel; methane; hydrogen; nheptane; methanol; DNS; simulation; openFoam; mixture-averaged; RCCI; ignition wave;

    Abstract : Two major fuels commonly used in compression ignition (CI) and spark ignition (SI) enginesare diesel and gasoline. The reserve of diesel and gasoline is limited, however the combustion ofthese fuels giving rise to air pollution. READ MORE

  7. 5. Developing Computational Methods for Moored Floating Wave Energy Devices

    Author : Johannes Palm; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave Power; RANS simulations; Discontinuous Galerkin; Mooring Dynamics;

    Abstract : Floating point absorbers are a common class of wave-power devices typically designed to move with large amplitude in energetic waves. This stands in sharp contrast to traditional marine design, where the wave-excited motions of the structure are preferably kept to a minimum. READ MORE
