Effect of HBr on Explosion Limits of Stoichiometric Hydrogen‐oxygen Mixture

International Journal of Chemical Kinetics, EarlyView.
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.

DNS of turbulence backscatter in a laboratory-scale swirl stabilized aero-combustor

Applications in Energy and Combustion Science
Classical theories of turbulence suggest that the kinetic energy cascade in nonreacting flows has a net transfer of energy from large to small scales. However, previous studies demonstrated that the thermal expansion of premixed flames can reverse the ...

Numerical study on the combustion process in a gas turbine combustor with different reference velocities

Advances in Aerodynamics, 2023
The mixing and combustion processes under different reference velocities in a gas turbine combustor were numerically investigated using the Flamelet Generated Manifold (FGM) model based on the Reynolds Averaged Navier–Stokes (RANS) method.

Flame‐Assisted Modification of Glass Wettability: Preliminary Results

Macromolecular Symposia, EarlyView.
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 ...

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

Journal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.
