Flame propagation characteristics and gas-phase oxidation of nitrous oxide and propane

Case Studies in Thermal Engineering
Nitrous oxide and fuel blends propellant as one of the substitutes for highly toxic hydrazine are under investigation. This study investigated the flame structure and dynamics of stoichiometric nitrous oxide and propane mixture (N2O/C3H8) by using ...

Flame acceleration studies in the MINIFLAME facility

, 1989
Flame acceleration and deflagration-to-detonation transition (DDT) studies have been conducted in a 19.4-cm high, 14.5-cm wide, and 2. 242-m long channel (MINIFLAME) that is a 1:12.6 scale model of the 136-m{sup 3} FLAME facility. Tests were conducted with two levels of hydrogen concentration -- 20% and 30%, with and without obstacles in the channel ...

Advanced Technologies for Characterizing and Detecting Battery Thermal Failure: A Review

Advanced Science, EarlyView.
Illustration of advanced characterization techniques to predict battery thermal failure. ABSTRACT Energy storage is essential in accelerating the global transition toward clean and sustainable energy across various sectors. Lithium‐ion batteries (LIBs) have become increasingly significant for energy storage due to their high energy density, low ...

Effect of Longitudinal Oscillations on Downward Flame Spread over Thin Solid Fuels [PDF]

Downward flame spread rates over vertically vibrated thin fuel samples are measured in air at one atmospheric pressure under normal gravity. Unlike flame spread against forcedconvective flows, the present results show that with increasing vibration ...

Gas flame acceleration in long ducts [PDF]

Journal of Loss Prevention in the Process Industries, 2015
In many practical situations, a flame may propagate along a pipe, accelerate and perhaps transform into a devastating detonation. This phenomenology has been known, more or less qualitatively, for a long time and mitigation techniques were proposed to try and avoid this occurrence (flame arresters, vents,...).

Dynamic Supramolecular Polyurethane Elastomers Enabling Bioinspired Strain‐Adaptive Stiffening to Resolve the Softness–Strength Paradox

Advanced Science, EarlyView.
Segmental‐level molecular engineering of a supramolecular polyurethane elastomer integrates strain‐adaptive chains, soft elastic segments, and dynamic hydrogen bonding motifs. This design reconciles skin‐like softness with muscle‐level strength, offering a sustainable and high‐performance material platform for next‐generation artificial skin and soft ...

Ignition of Deflagration and Detonation Ahead of the Flame due to Radiative Preheating of Suspended Micro Particles [PDF]

, 2015
We study a flame propagating in the gaseous combustible mixture with suspended inert particles. The gas is assumed to be transparent for the radiation emitted by the combustion products, while particles absorb and re-emit the radiation. Thermal radiation

Highly Efficient and Environmentally Stable Radiative Cooling Fabric: Integrating Photoluminescence and Hierarchical Core–Shell Fibers

Advanced Science, EarlyView.
A scalable radiative cooling fabric engineered with a multi‐layer assembly core–shell structure and integrated photoluminescent materials is reported. The fabric exhibits remarkable environmental stability, including UV resistance, mechanical durability, hydrophobicity, stain resistance, thermal stability, and flame retardancy, demonstrating its ...
