Characteristics Of Large Diffusion Flames Burning In A Vitiated Atmosphere [PDF]
, 1991 Experiments concerning properties of large diffusion flames burning steadily in a vitiated atmosphere under conditions similar to those which may arise in a room fire are described. The effects of vitiation on the products of combustion and flame lengths,

Gas Diffusivity in the Forest Humus Layer
Soil Science, 2019 While several diffusivity models have been developed for mineral soils, there are few data for the forest humus layers that overlie, and are distinct from, the mineral soil. We measured soil gas diffusivity of the organic layer of spruce and beech stands.

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution
Advanced Engineering Materials, EarlyView.Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Liquid-Water Interactions with Gas-Diffusion-Layer Surfaces [PDF]
Journal of The Electrochemical Society, 2014 Understanding dynamic liquid-water uptake and removal in gas-diffusion layers (GDLs) is essential to improve the performanceof polymer-electrolyte fuel cells and related electrochemical technologies. In this work, GDL properties such as breakthroughpressure, droplet adhesion force, and detachment velocity are measured experimentally for commonly used ...

Advanced Engineering Materials, EarlyView.Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.
