Numerical investigation of high-pressure combustion in rocket engines using Flamelet/Progress-variable models

open access: yes, 2014
The present paper deals with the numerical study of high pressure LOx/H2 or LOx/hydrocarbon combustion for propulsion systems. The present research effort is driven by the continued interest in achieving low cost, reliable access to space and more ...

Non‐Flammable Electrolytes for Safe Lithium‐, Sodium‐, and Potassium‐Ion Batteries

open access: yesElectron, Volume 3, Issue 4, November 2025.
This review highlighted recent progress in non‐flammable electrolytes for lithium‐, sodium‐, and potassium‐ion batteries (PIBs). It explores diverse flame‐retardant systems, including organophosphorus, halogenated, ionic liquid, aqueous, and solid‐state types, emphasizing their safety mechanisms, electrochemical performance, and compatibility.

On the Structure and Stabilization Mechanisms of Planar and Cylindrical Premixed Flames [PDF]

open access: yes
The configurational simplicity of the stationary one-dimensional flames renders them intrinsically attractive for fundamental flame structure studies. The possibility and fidelity of studies of such flames on earth, however, have been severely restricted

An efficient flamelet progress-variable method for modeling non-premixed flames in weak electric fields

open access: yes, 2017
Combustion stabilization and enhancement of the flammability limits are mandatory objectives to improve nowadays combustion chambers. At this purpose, the use of an electric field in the flame region provides a solution which is, at the same time, easy ...

Measurement and Identification of Flame Describing Function (FDF) Based on Parallel Subsystem Model

open access: yesAerospace
Because of the need for low pollutant emissions, industrial gas turbines typically use partially premixed gases for combustion. However, the nonlinear dynamic characteristics of partially premixed flames have not been studied sufficiently.

Flame structure simulation in a methane/air coflow partially premixed burner

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2014
The effect of the equivalence ratio on the partially premixed methane / air laminar flame structure, in a coflow atmospheric burner was simulated. Three equivalence ratios were studied (Φ=1.6, Φ=2.0, Φ=3.5) keeping constant the released energy.
