A Survey on Wind Turbine Condition Monitoring and Fault Diagnosis—Part I: Components and Subsystems
IEEE transactions on industrial electronics (1982. Print), 2015This paper provides a comprehensive survey on the state-of-the-art condition monitoring and fault diagnostic technologies for wind turbines (WTs). The Part I of this survey briefly reviews the existing literature surveys on the subject, discusses the ...

Pneumatized inferior turbinate
American Journal of Otolaryngology, 1999The inferior turbinate is a separate bone that extends from the body of the maxilla to the ethmoidal crest. Its arched central portion overhangs the so-called inferior meatus, which contains the opening of the nasolacrimal duct. The inferior turbinate is part of the nasal valve area, which is the narrowest part of the nose.

Bilateral accessory inferior turbinates and secondary middle turbinates
Japanese Journal of Radiology, 2012Bifid inferior nasal turbinates-two inferior turbinates with a single root observed in the nasal cavity-are an extremely rare anatomical variation, especially when they are observed bilaterally and exist with other variations. We report a case of bilateral bifid inferior nasal turbinates with bilateral secondary middle turbinates.

Simulation comparison of wake mitigation control strategies for a two‐turbine case
, 2015Wind turbines arranged in a wind plant impact each other through their wakes. Wind plant control is an active research field that attempts to improve wind plant performance by coordinating control of individual turbines to take into account these turbine–

A Wind Farm Reliability Model Considering Both Wind Variability and Turbine Forced Outages
IEEE Transactions on Sustainable Energy, 2017This paper presents an analytical method to model the output of large wind farms for power system reliability assessment. The model considers the variability of wind, random failures (forced outages) of turbines, as well as the correlation between ...

Effect of tower and nacelle on the flow past a wind turbine
, 2017Large eddy simulations (LES) of the flow past a wind turbine with and without tower and nacelle have been performed at 2 tip speed ratios (TSR, λ=ωR/U∞), λ=3 and 6, where the latter corresponds to design conditions.

On the Cooling of Gas Turbines
2001This article deals with measurements of convective heat transfer coefficients in three fluid flow patterns that concern both internal and external cooling of gas turbine components; in particular, the flow in a couple of smooth, or ribbed, ducts connected by a 180° sharp turn, a jet in cross-flow, and a jet impinging on a wall for short nozzle-to-wall ...
