Variable Pitch Darrieus Water Turbines
Journal of Fluid Science and Technology, 2008 In recent years the Darrieus wind turbine concept has been adapted for use in water, either as a hydrokinetic turbine converting the kinetic energy of a moving fluid in open flow like an underwater wind turbine, or in a low head or ducted arrangement ...

Non-Empirical BEM Corrections Relating to Angular and Axial Momentum Conservation
Energies, 2019 The Blade-Element Momentum (BEM) model for Horizontal-Axis Wind Turbines (HAWTs), although extremely useful, is known to be approximate due to model formulation insufficiencies, for which add-ons and corrections have been formulated over the past many ...

A Multi-Element Diffuser Augmented Wind Turbine
Energies, 2014 A new class of diffuser augmented wind turbines (DAWTs) is presented. The new diffuser concept exploits aero-dynamic principles for the creation of high-lift airfoil configurations known from the aircraft industry.

Random partitions in statistical mechanics [PDF]
, 2014 We consider a family of distributions on spatial random partitions that provide a coupling between different models of interest: the ideal Bose gas; the zero-range process; particle clustering; and spatial permutations.

A chain of interacting particles under strain [PDF]
, 2011 We investigate the behaviour of a chain of interacting Brownian particles with one end fixed and the other end moving away at slow speed epsilon > 0, in the limit of small noise.

Rotor aerodynamic power limits at low tip speed ratio using CFD [PDF]
, 2014 When investigating limits of rotor aerodynamic models, the Betz limit serves as a solid marker of an upper limit which no model should be able to exceed. A century ago Joukowsky (1912) proposed a rotor aerodynamic model utilizing a rotating actuator disc

Nordic Journal of Botany, EarlyView.Many habitat‐specialist plant species have been endangered by fragmentation or destruction of their habitats. Minuartia smejkalii is a serpentinophyte endemic to the Czech Republic. It is highly threatened by recent habitat destruction and fragmentation, calling for effective conservation measures.
