Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure

Structural Concrete, EarlyView.
Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.

Measurement of Fuel Concentration Profile at Leading Edge of Lifted Flame with Acetone Laser-Induced Fluorescence

Journal of Thermal Science and Technology, 2009
This is a study of the leading-edge characteristics of a methane-air triple flame. Few experiment results are available for physical examination of such characteristics, so further experimental investigations are strongly needed to understand the ...

An efficient flamelet progress-variable method for modeling non-premixed flames in weak electric fields

, 2017
Combustion stabilization and enhancement of the flammability limits are mandatory objectives to improve nowadays combustion chambers. At this purpose, the use of an electric field in the flame region provides a solution which is, at the same time, easy ...

Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

High Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Flamelet/progress variable modelling of turbulent non-premixed cool flames of dimethyl-ether/methane mixtures

Green Energy and Resources
In present work, the turbulent non-premixed cool flames of dimethyl-ether (DME)/methane mixtures are studied within the framework of flamelet/progress variable modelling and chemical kinetic analyses.

‘Enthusiasts’ and ‘Fanatics’: The Decembrists as a Case Study in French Influence on Russian Culture, Emotions and Thought

History, EarlyView.
Abstract Participants in Russia's 1825 Decembrist uprising against the Tsarist regime were, quite literally, a case study in French cultural influence upon Russia. This is particularly true as it relates to Russia's emotional cultures. Although this has not, traditionally, been the primary focus of historical analysis of this event (in Soviet or ...

Queen Anne's Wardrobe: Fashion, Sartorial Politics, and the Representational Strategies of the Last Stuart Queen

Journal for Eighteenth-Century Studies, EarlyView.
Abstract The final Stuart monarch, Queen Anne, has often been overlooked in studies of visual and material culture, particularly of fashion and dress. This article is the first to undertake a qualitative and quantitative analysis of the wardrobe accounts of Queen Anne, situating her consumption within the context of the eighteenth‐century fashion ...

Assessment of implementation variants of conditional scalar dissipation rate in LES-CMC simulation of auto-ignition of hydrogen jet

Archives of Mechanics, 2013
In this paper the large eddy simulation (LES) and conditional moment closure (CMC) combustion model have been applied for modelling of auto-ignition of hydrogen jet issuing into a hot ambient co-flow.
