One of the most essential inherent characteristics a combustible mixture is laminar burning velocity. Because its relevance, many methods for measuring flame velocity have been devised. advanced procedure was used to derive in constant volume vessel blends iso-octane and n-heptane/air mixtures this study: particle imaging velocimetry. Based on precise flow field with vectors, velocimetry (PIV) ...

conclusions prf of the trigeminal ganglion should be further evaluated as an alternative treatment method for tn. results the percentages of patients who showed excellent pain relief (≥ 80% pain relief) at 2, 6, and 12 months were 73.5% (25/34), 61.8% (21/34), and 55.9% (19/34), respectively. the percentages of patients showing satisfactory pain relief (50–80% pain relief) at 2, 6, and 12 month...

Flash boiling spray has been regarded as a promising fuel injection technology. Many investigations have focused on physics and mechanisms of flash spray, but information alcohols in GDI engines is very limited. In this paper, the characteristics, flame propagation, combustion analysis, PN emissions butanol isomers under studied. A constant volume chamber with high-speed camera used to investig...

There is an increasing demand for kinetic models of surrogate components to predict the combustion and emissions real fuels. In this paper, a new fuel mechanism, C3MechV3.3, proposed by Computational Chemistry Consortium (C3). This mechanism constructed based on C0 – C4 core with important species interest in complex surrogates such as hexane isomers, n-heptane, iso-octane, nC8 nC12 linear alka...

<div class="section abstract"><div class="htmlview paragraph">Computational fluid dynamics (CFD) modeling has many potentials for the design and calibration of modern future engine concepts, including facilitating exploration operation conditions casting light on involved physical chemical phenomena. As more attention is paid to matching different fuel types combustion strategies, u...

Carbonaceous soot produced in a small diesel engine test facility was investigated with ultra-small-angle X-ray scattering. Three soot samples produced using a reference diesel fuel and the reference fuel plus two oxygenate additives were investigated. The presence of objects at three typical size ranges, i.e., aggregates, primary particles, and subunits, was observed. By studying soot powders ...

Purpose To investigate the relation between optical properties, population receptive fields (pRFs), visual function, and subjectively perceived quality of vision after cataract surgery. Methods The study includes 30 patients who had recently undergone bilateral sequential cataract surgery. We used functional magnetic resonance imaging and pRF modelling methods to assess pRF sizes across visua...
