| Tidal energy converters are mostly marine turbines. They have many disavantages in sea where the environment is very inhospitable. We study a new system based on undulating membrane. Pressure deforms the device periodically, we observe a wave propagating along the length. Electromagnetic converters are distributed over the length of the membrane and act like dampers. In this paper, we present numerical and experimental developments carried out to study the system’s behavior. |

| This manuscript presents three approaches : analytical, experimental and numerical, to study the behaviour of a flexible membrane tidal energy converter. This technology, developed by the EEL Energy company, is based on periodic deformations of a pre-stressed flexible structure. Energy converters, located on each side of the device, are set into motion by the wave-like motion. In the analytical model, the membrane is represented by a linear beam model at one dimension and the flow by a 3 dimensions potential fluid. The fluid forces are evaluated by the elongated body theory. Energy is dissipated all over the length of the membrane. A 20th scale experimental prototype has been designed with micro-dampers to simulate the power take-off. Trials have allowed... |
