Wave and Tidal Energy

Wave and Tidal Energy CFD

CFD modelling of wave and tidal energy and novel floating wind energy concepts can be assessed in terms of their hydrostatic stability, motion response, power absorption, wave, current and mooring loads. Connecting forces between coupled bodies in waves and currents, automatically take into account fluid viscosity derived forces. Extreme wave survival loads on static and floating structures using solitary focused waves or short duration large irregular waves are also feasible. The unique combination of advanced free surface tracking and flexibility to model several connected moving objects without the need to re-mesh enables complex body motions in response to wave and current forces to be accounted for, including the detection of power dissipating parametric roll and pitch motions which can result from dynamic changes in hydrostatic stiffness.  Motion decay tests in any of the six degrees of freedom and natural oscillation periods and drag coefficients can be extracted and used to supplement more extensive radiation diffraction based simulations in irregular seas, leading to a more realistic motion response and power absorption than would be achieved using potential flow based methods alone.
