Simulating wind turbine interactions using the vorticity transport equations [PDF]
, 2009 The aerodynamic interactions that can occur within a wind farm result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.

Electroactive Liquid Crystal Elastomers as Soft Actuators
Advanced Functional Materials, EarlyView.Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.

Non-equilibrium steady states for chains of four rotors
, 2016 We study a chain of four interacting rotors (rotators) connected at both ends to stochastic heat baths at different temperatures. We show that for non-degenerate interaction potentials the system relaxes, at a stretched exponential rate, to a non ...

Performance of multi-stage axial-flux machines with MMEs
The Journal of Engineering, 2019 This study covers the investigation into the reduction of rare-earth magnets in a permanent magnet (PM) machine via the use of multiple rotors to enable a PM generator to be comprised of mixed magnetic elements, hereafter referred to as MME, by ...
