Computer Controlled Waves Energy Unit (EOMC)
PL-107468
The "EOMC" Computer Controlled Waves Energy Unit, developed by EDIBON, provides a scaled-down platform for studying wave energy and examining the effects of various influencing factors. This unit consists of a Base Service Unit and Waves Generator ("EOMC-UB"), along with several compatible modules that enable exploration of wave-to-mechanical energy conversion processes.
The base "EOMC-UB" unit primarily comprises a flow channel and wave generator. The flow channel is a transparent rectangular section (80 x 300 mm, 5 m in length) that facilitates the controlled movement of water. Water is circulated from a storage tank via a computer-controlled hydraulic pump, which directs it to an inlet tank for stabilization. The water then flows through the channel to the reception tank, finally returning to the storage tank, creating a closed-loop system. A wave sensor placed within the channel allows for the measurement of wave height and frequency.
Water flow regulation through the channel is achieved with a control valve at the pump outlet, where a flow sensor measures the water flow rate. A differential pressure sensor is also positioned at the pump's water outlet to measure pressure drops, either at the orifice plate or within the Venturi tube. The waves are generated by a blade mechanism, which pulls water to create various wave forms. Wave frequency is adjusted by varying the blade's rotational speed, which is computer-controlled, while wave size can be changed by modifying the water level in the tank or adjusting the blade’s depth within the channel. Additionally, a speed sensor monitors the blade's rotational speed, enabling comprehensive data collection and analysis.
Through this detailed setup, the "EOMC" unit provides a complete and versatile environment for studying the mechanics of wave energy and related variables.
