Abstract:   (327 Views)
Oscillating hydrofoils in presence of waves under the free surface as new systems for energy extraction is a hybrid renewable marine energy sources. In this system energy extraction is associated with oscillating hydrofoils operating as biomimetic systems in harmonic waves and currents in coastal regions using active pitch control. Another way of energy exploiting is used by installation of foils under the hull of the ships. Flapping foils located beneath the hull of the ship are investigated as unsteady thrusters, augmenting ship propulsion in rough seas and offering dynamic stabilization. In this system the foil undergoes a combined oscillatory motion in the presence of waves. For the system in the horizontal arrangement, the vertical heaving motion of the hydrofoil is induced by the motion of the ship in waves. The survey shows that exploiting of energy from sea using these techniques can be proposed for Iranian hybrid ships for their propulsion as secondary source of energy. Particularly North part of Persian Gulf has a proper situation for installation and operation as marine energy device in coastal regions.
