Journal of Physics: Conference SeriesAbstract Flame spread over solid fuel is a fundamental problem in fire safety science. Although it has been studied in different orientations – downward, upward, horizontal, and lateral – closed-form formula for predicting the flame spread rate is only available for opposed-flow configuration and has been experimentally verified in ...

Upward Flame Spread over Discrete Fuels [PDF]
, 2014 Upward flame spread over discrete fuels has been analyzed through experimental research on vertical arrays of alternating lengths of PMMA and insulation. By manipulating the lengths of the PMMA fuel and the insulation, several important trends related to

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines
Advanced Engineering Materials, EarlyView.Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Critical Criterion for Flame Spread Acceleration of Concave Surfaces with Different Curvatures
FireConcave surface is a common geometry in both industrial buildings and natural environments; the flame spread behaviors on this special surface are worth studying, while few studies have been completed yet.

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Journal of Combustion, 2022 Fire occurring in the chaparral behaves as a crown fire, a dual-layer fire that typically ignites in a dead surface fuel layer and transitions to an elevated live crown layer where it continues to spread.
