On the Influence of Antioxidants and Recycled MgO–C Source Material on the Mechanical Properties of Carbon‐Bonded Magnesia Refractories

Advanced Engineering Materials, Volume 28, Issue 10, 20 May 2026.
The presented study focuses on the fracture behaviour of carbon‐bonded magnesia MgO–C refractories, where environmentally friendly fructose, collagen and lignin serve as temporary binding agents. The partial substitution of the source material with recycled MgO–C reduces the fracture resistance, which can be counteracted by the additional introduction ...

Investigation of partially-premixed combustion in a household cooker-top burner

Fuel Processing Technology, 2016
Abstract The present paper provides an examination of the CH 4 /air flame in a self-aerated cooker-top burner currently in production. The operating conditions, the design characteristics and their effects on the combustion were investigated by calculating velocity, turbulence, temperature and reactive scalars using a modified temperature-composition

Partially Premixed Combustion Application for Diesel Power Improvement [PDF]

Volume 1: Large Bore Engines; Fuels; Advanced Combustion, 2017
A partially premixed combustion (PPC) approach was applied in a single cylinder diesel research engine in order to characterize engine power improvements. PPC is an alternative advanced combustion approach that generally results in lower engine-out soot and NOx emission, with a moderate penalty in engine-out unburned hydrocarbon (UHC) and carbon ...

Evaluation of a High‐Performance Monopropellant Formed of Microencapsulated Hydrocarbon Fuels in Combination With Gelled Hydrogen Peroxide in a Strand Burner Setup

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 5, Page 781-789, May 2026.
A high‐performance premixed monopropellant is prepared from hydrocarbon‐filled microcapsules and hydrogen peroxide. This propellant is burned in a strand burner, and the effect of different parameters on the burn rate is evaluated. ABSTRACT A dispersion of hydrocarbon‐fuel‐filled microcapsules in gelled hydrogen peroxide can form a premixed ...

Combustion regimes in sequential combustors: Flame propagation and autoignition at elevated temperature and pressure

, 2018
This numerical study investigates the combustion modes in the second stage of a sequential combustor at atmospheric and high pressure. The sequential burner (SB) features a mixing section with fuel injection into a hot vitiated crossflow.

Imaging gas in a combustion engine with high‐energy X‐ray Compton scattering

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 788-793, May 2026.
Compton‐scattering imaging has been applied to a combustion engine under operation for the first time. With a time‐resolved technique, a crank‐angle dependency of Compton‐scattered X‐ray intensity is obtained at different positions in a combustion chamber.We have developed a time‐resolved Compton‐scattering imaging technique for visualizing gas ...
