Recently, wind farms consisting of clusters of closely spaced vertical-axis wind turbines (VAWTs) have attracted the interest of many people. In this study, a method using a wake model to predict the flow field and the output power of each rotor in a ...

Biological activity in the wake of an island close to a coastal upwelling [PDF]
Hydrodynamic forcing plays an important role in shaping the dynamics of marine organisms, in particular of plankton. In this work we study the planktonic biological activity in the wake of an island which is close to an upwelling region.

Validation of wind turbine wake models with focus on the dynamic wake meandering model [PDF]
This analysis compares current wake models, such as the Sten Frandsen turbulence model, an engineering wind speed deficit and turbulence model developed by G. Chr. Larsen, the N. O. Jensen wind speed deficit description and three variations of the dynamic wake meandering (DWM) model to measurements from onshore wind farms. Special attention is given to

An Aero-acoustic Noise Distribution Prediction Methodology for Offshore Wind Farms
Recently attention has been paid to wind farm noise due to its negative health impact, not only on human beings, but also to marine and terrestrial organisms. The current work proposes a numerical methodology to generate a numerical noise map for a given

Upstream-radiated rotor–stator interaction noise in mean swirling flow [PDF]
A major component of the noise in modern aeroengines is rotor–stator interaction noise generated when the wake from the rotating fan impinges on a stator row downstream.

A simple model of wake capture aerodynamics
Flapping wings may encounter or ‘capture’ the wake from previous half-stroke, leading to local changes in the instantaneous aerodynamic force on the wing at the start of each half-stroke. In this paper, I developed a simple approach to integrating prediction of these wake capture effects into existing analytical quasi-steady models for hovering insect ...

Clarification of influences of inflow conditions on wake of horizontal axis wind turbine
In recent years, wind turbines are introduced in wind farms in which some wind turbines are concentrated. When wind turbines are built in contiguity with each other in wind farms, the flow passing through a wind turbine, which is called wake, may flow ...

Mathematical models for sleep-wake dynamics: comparison of the two-process model and a mutual inhibition neuronal model [PDF]
Sleep is essential for the maintenance of the brain and the body, yet many features of sleep are poorly understood and mathematical models are an important tool for probing proposed biological mechanisms.

Study of Generalized Interaction Wake Models Systems with ELM Variation for Off-Shore Wind Farms
This paper reports a novel frandsen generalized wake model and its variation model-frandsen generalized normal distribution wake model for off-shore wind farms. Two different new wake models in off-shore wind farms have been studied comparatively.
