An Experimental Study on the Darrieus-Savonius Turbine for the Tidal Current Power Generation

Journal of Fluid Science and Technology, 2008
The Darrieus turbine is popular for tidal current power generation in Japan. It is simple in structure with straight wings rotating around a vertical axis, so that it has no directionality against the motion of tidal flow which changes its direction ...

Acute Hypoxia Decreases Maximum Fat Oxidation Rate During Step Incremental Exercise Normalized to Respiratory Compensation Point

European Journal of Sport Science, Volume 26, Issue 2, February 2026.
ABSTRACT Whether fat oxidation (FATox) is altered during exercise in hypoxia remains equivocal due to differences in experimental protocols. Furthermore, to date no investigation has reported the effect of hypoxia on maximal fat oxidation rate (MFO).

Design, commissioning and performance of a device to vary the turbulence in a recirculating flume

, 2013
Ambient turbulent flow structures are one of the key drivers that will determine the rate of wake recovery downstream of tidal turbines. For second and third generation arrays or farms such a parameter is critical for the determination of inter-device ...
