2. 1. Numerical Modelling and Mechanical Studies on a Point Absorber Type Wave Energy Converter

   Author : Yue Hong; Rafael Waters; Mikael Eriksson; Cecilia Boström; Jørgen Hals Todalshaug; Uppsala universitet; []
   Keywords : linear generator; point absorber; numerical modelling; power production; optimal damping; Teknisk fysik; Engineering Science;

   Abstract : Oceans cover two thirds of the Earth’s surface and the energy potential of ocean waves as a renewable energy source is huge. It would therefore be a tremendous achievement if the vast mechanical energy in waves was converted into a form of energy that could be used successfully by society. READ MORE
