Hydraulic PTO model emulator for WEC tank tests
2018 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2018 In order to accelerate the overall power take off (PTO) design effort and to cheaply evaluate alternative designs, the construction of the real hydraulic PTO can be replaced with the design of a hydraulic PTO model emulator. This has the added advantage that it can be applied at model testing scales, where real hydraulic hardware would not give ...

GAMM-Mitteilungen, Volume 46, Issue 2, June 2023., 2023 Abstract Dielectric elastomers are a promising technology for wave energy harvesting. An optimal system operation can allow maximizing the extracted energy and, simultaneously, reducing wear that would lead to a reduction in the wave harvester lifetime.

Enhancing Thermo‐Osmotic Low‐Grade Heat Recovery by Applying a Negative Pressure to the Feed
Global Challenges, Volume 7, Issue 4, April 2023., 2023 Thermo‐osmotic energy conversion is supposed to convert low‐grade heat into power. The efficiency can be improved by applying negative pressure to the feed liquid. The theoretical calculation, computational fluid dynamics simulation, and experiments are carried out to verify the method.

International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023 An air‐type photovoltaic‐thermal collector (PVTC) is a solar collector that generates heated air and electricity from the incident solar energy in a single system. Adding a heat transfer device to this PVTC improves its performance but also increases the power consumption of the fan.
