Analysis of Wake Turbulence for a Savonius Turbine for Malaysia’s Slow-Moving Current Flow

International Journal of Renewable Energy Development, 2022
With Malaysia being surrounded by water bodies, tidal energy could be used for energy extraction. While several turbine designs and technologies have been used for tidal energy extraction, information on the use of vertical-axis tidal turbines (VATTs ...

Flow‐controlled expiration improves gas exchange in anaesthetised horses undergoing orthopaedic surgery

Equine Veterinary Journal, EarlyView.
Abstract Background Flow‐controlled expiration (FLEX) has been shown to significantly enhance oxygenation in horses under laboratory conditions. Objective This study aims to corroborate these findings by evaluating the effects of FLEX on gas exchange in a randomised clinical trial involving a large population of clinical horses undergoing orthopaedic ...

How do physiological networks respond to normobaric hypoxia and isometric exercise?

Experimental Physiology, EarlyView.
Abstract The dynamics of physiological systems are impacted by both exercise and hypoxia. Network models can be used to map the interactions between various physiological components in environmental physiology and exercise using the concepts of information theory.

Evaluating Mechanical Strength in Vertical-Axis Tidal Turbines: A Comparative Study of Internal Blade Structure and Material Selection through CFD Simulation [PDF]

E3S Web of Conferences
Due to the density of water, tidal turbine blades are subject to significantly greater stresses than wind turbine blades. Multiple blade failures occurred during prototype testing as a result of loading conditions and protracted exposure to seawater ...

Cavitation limits on tidal turbine performance [PDF]

Ocean Engineering, 2018
Abstract Blockage effects are currently not accounted for in cavitation analyses of tidal turbine rotors. At higher blockage ratios, rotors are more heavily loaded and have potentially stronger suction peaks, so cavitation inception is more likely. In this paper, blade resolved computations are used to carry out a cavitation analysis over a range of ...

Design and testing of a contra-rotating tidal current turbine [PDF]

, 2005
A contra-rotating marine current turbine has a number of attractive features: nearzero reactive torque on the support structure, near-zero swirl in the wake, and high relative inter-rotor rotational speeds.

Combined multi‐metric assessment of diaphragm contractile function in healthy humans: Feasibility, validity and reliability

Experimental Physiology, EarlyView.
Abstract The combined use of subcostal ultrasonography and respiratory manometry represents a novel, integrative method for quantifying diaphragm contractile function (force, velocity and power). We evaluated the technical feasibility, construct validity and within‐day test–retest reliability of this method during non‐volitional, volitional and ...
