Experimental Investigation into the Effects of Thermal Recuperation on the Combustion Characteristics of a Non-Premixed Meso-Scale Vortex Combustor

Energies, 2018
In small-scale combustors, the ratio of area to the combustor volume increases and hence heat loss from the combustor’s wall is significantly enhanced and flame quenching occurs.

Optimizing Ball‐Milled Composites for Fast Energy Release Under Shock Compression

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters

Theory of gaseous combustion [PDF]

, 1984
The combustion processes are characterised by two non linear feedback mechanisms producing self-acceleration. One is of a thermal nature and the other is purely chemical.

Surface engineering of recycled high‐density polyethylene‐based wood–polymer composites via carbon black‐containing surface film coating

Coloration Technology, EarlyView.
Abstract This study evaluates carbon black nanoparticle (CB NP)‐reinforced surface films for improving the durability, thermal stability, fire performance and mechanical retention of recycled high‐density polyethylene (HDPE)‐based wood‐plastic composites (WPCs) after 12 months of natural weathering.

Effects of swirl on intermittency characteristics in turbulent non-premixed flames [PDF]

, 2012
Swirl effects on velocity, mixture fraction and temperature intermittency have been analysed for turbulent methane flames using LES. The LES solves the filtered governing equations on a structured Cartesian grid using a finite volume method, with ...

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures

Journal of Raman Spectroscopy, Volume 57, Issue 10, Page 1644-1653, October 2026.
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO 2 and the v2 mode of CH 4. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH 4 and CO 2 spectra in a diffusion flame.

Engineering Phosphorus‐Modified Flame‐Retardant Thermoplastic Polyurethane via Reactive Melt Processing

Journal of Polymer Science, Volume 64, Issue 19, Page 4131-4156, 1 October 2026.
Phosphorus‐modified TPUs are prepared by one‐step, solvent‐free reactive melt processing using phosphate‐ or phosphonate‐containing diols and PEG or PPG soft segments. Fire behavior and mechanical response depend strongly on both chemistries. Peak heat release rate decreases by up to 54%, but reduced tensile strength and V‐2 dripping behavior reveal a ...
