HARBOR SURGING

open access: yesCoastal Engineering Proceedings, 1950
Surge is the name applied to wave motion with period intermediate between that of ordinary wind waves and that of the tides; say from one to sixty minutes. An additional characteristic of surge is that it is usually of very low height; perhaps 0.3 ft. is typical.

Investigation of Vaned-Recessed Casing Treatment in a Low-Speed Axial Flow Compressor, Part I: Time-Averaged Results

open access: yesAerospace, 2023
This paper investigates the effects of two modifications to a vaned recessed casing treatment. First, the shape of a circular curve was used in the top of the treated casing. Second, a fully curved guide vane was also applied.

The aerodynamics of a blade pitch, rotor speed, and surge step for a wind turbine regarding dynamic inflow

open access: yesWind Energy, 2022
Floater motions introduce unsteadiness in the aerodynamics of floating offshore wind turbines. The aerodynamics of a wind turbine after three perturbations are studied: a blade pitch step, a rotor speed step for which dynamic inflow is expected, and a ...

Differentiating Large‐scale Surge versus Daily Surge [PDF]

open access: yesAcademic Emergency Medicine, 2006
This breakout session at the Academic Emergency Medicine 2006 Consensus Conference examined how baseline overcrowding impedes the ability of emergency departments to respond to sudden, unexpected surges in demand for patient care. Differences between daily and catastrophic surge were discussed, and the need to invoke a hospital‐wide response to surge ...

Research on Online Diagnosis Method of Fuel Cell Centrifugal Air Compressor Surge Fault

open access: yesEnergies, 2021
Stable operation of fuel cell air compressions is constrained by rotating surge in low flowrate conditions. In this paper, a diagnosis criterion based on wavelet transform to solve the surge fault is proposed. First of all, the Fourier transform was used

Sustained investment surges [PDF]

open access: yesOxford Economic Papers, 2019
AbstractExisting empirical studies have mainly focused on determinants of average investment levels. Instead, we investigate episodes of accelerated capital stock growth having a duration of eight years or longer. We find that episodes are relatively common, even in low-growth regions, but more so in middle-income and Asian countries. After identifying

Time to surge concept and surge control for acceleration performance [PDF]

open access: yesIFAC Proceedings Volumes, 2008
Surge is a dangerous instability that can occur in compressors. It is avoided using a valve that reduces the compressor pressure.

Covid-19: US faces “surge upon a surge” [PDF]

open access: yesBMJ, 2020
The US is likely to experience “a surge upon a surge” of covid-19 cases as a result of millions of people traveling over the Thanksgiving holiday weekend (26-29 November) to celebrate with family and friends, the leading US expert on the disease has predicted.1 Although the Centers for Disease Control and Prevention (CDC) asked people to stay home for
