Phosphorus flame retardants with different chemical environment. Thermal stability and flame-retardant efficiency [PDF]
, 2022 16Engineering plastics (PA, PBT) have their own high processing temperatures (250-350°C and even higher). To realize fire-resistant polymers it is necessary to compound polymers and flame retardants at these temperatures without a serious change in the ...

Study on flame stability in oxygen-enriched ammonia/N2/O2 laminar diffusion flame
Nihon Kikai Gakkai ronbunshu, 2018 Ammonia is regarded as one of the alternative fuels because CO2 is not emitted during the combustion process of ammonia. The physical properties of ammonia are suitable for transportation and storage as a “hydrogen carrier”.

Intrinsic instability of flame-acoustic coupling [PDF]
, 2014 This paper shows that a flame can be an intrinsically unstable acoustic element. The finding is clarified in the framework of an acoustic network model, where the flame is described by an acoustic scattering matrix.

Effect of N2 Replacement by CO2 in Coaxial-Flow on the Combustion and Emission of a Diffusion Flame
Energies, 2018 In this study, a double concentric burner burning methane with an annular coaxially-flowing oxidizer was adopted to operate the diffusion flame in lifted flame regime. The effects of coaxial-flow velocity, coaxial-flow composition variation through total

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

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.

On Flame Stability In The Hysteresis Regime In Co-Flow [PDF]
, 2005 This study documents experiments performed on lifted turbulent diffusion flames in the hysteresis regime with air co-flow. Undiluted methane, ethylene, and propane were used as fuels and two nozzle sizes were used. The results confirm the non-linearity

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.
