Modeling and Analysis of Inertial-Hydraulic Power take-off Device

Journal of Physics: Conference Series
Abstract This paper introduces a novel power output device that combines inertia and hydraulics, which captures vibrations caused by external forces acting on the carrier in space using the sensitive gyroscope of the inertia system. The captured random mechanical energy is then converted into hydraulic energy, rectified and regulated by ...

Implementation of a Hydraulic Power Take-Off for wave energy applications [PDF]

, 2013
The main purpose of the following work is to implement a hydraulic power take-off system coupled with the dynamic model of a wave energy converter. In this work the Wavestar concept will be used without any losses of the general principle since the power take-off sub-model can be coupled with any device, if a relative motion between to body is ...

Optimizing the hydraulic power take-off system in a wave energy converter

Ocean Engineering
This study aims to determine the optimal pressure for the accumulator tank in a wave energy converter (WEC) with hydraulic power take-off (PTO) to maximize energy generation. A simulation-based approach was employed to analyze the buoy's performance with wave data generated from the Wafo toolbox using the generalized Pierson–Moskowitz (GPM) spectrum ...

Wave Energy Converters and Hydraulic Power Take-off: analysis of a possible control strategy

Journal of Physics: Conference Series, 2023
Abstract Wave energy conversion is one of the most promising but untapped worldwide technologies. In fact, wave energy is clean and renewable as the solar and wind ones, but also less mature and utilized. Moreover, several Wave Energy Converters (WECs) patents have been developed in the last decades, as evidence of the great potential ...

An Electrowetting Pump

Advanced Functional Materials, EarlyView.
A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐
