Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Recirculation in a combustion chamber is required for stabilizing the flame and reducing pollutants. The swirlers can generate recirculation in a combustion chamber, inducing a swirling flow that breaks vorticity and improves the mixing of air and fuel ...

Coherent Stokes Raman Scattering for Simultaneous Measurement of CO2 and CH4 Temperatures
A three‐beam hybrid fs/ps CSRS method is employed to excite the rovibrational transitions in the Fermi‐dyad of CO2$$ {}_2 $$ and the v2$$ {v}_2 $$ mode of CH4$$ {}_4 $$. Time‐domain spectroscopic models are developed to extract the fuel and flame temperature profiles from experimental CH4$$ {}_4 $$ and CO2$$ {}_2 $$ spectra in a diffusion flame ...

Effect of HBr on Explosion Limits of Stoichiometric Hydrogen‐oxygen Mixture
ABSTRACT This work, based on numerical simulations, discusses the effect of HBr as an inhibitor on the explosion limit of stoichiometric hydrogen‐oxygen gas mixture in a closed spherical vessel. The numerical simulation solves the complete governing equations for mass, momentum, species and energy.

Acoustic and Large Eddy Simulation studies of azimuthal modes in annular combustion chambers [PDF]
The objectives of this paper are the description of azimuthal instability modes found in annular combus- tion chambers using two numerical tools: (1) Large Eddy Simulation (LES) methods and (2) acoustic solv- ers.

Flame‐Assisted Modification of Glass Wettability: Preliminary Results
ABSTRACT Fog formation and moisture condensation limit the performance of glass surfaces in optical, microfluidic, and sensing applications, where stable transparency under humid conditions is essential. Enhancing surface wettability represents an effective strategy to mitigate these effects; therefore, the development of methods to tailor glass ...
