Front dynamics in turbulent media [PDF]

open access: yes, 1997
A study of a stable front propagating in a turbulent medium is presented. The front is generated through a reaction-diffusion equation, and the turbulent medium is statistically modeled using a Langevin equation.

Simulation of Nonpremixed Jet Flame Using Flamelet‐Generated Manifold

open access: yesSafety Science and Technology, Volume 1, Issue 1, March 2026.
A flamelet‐generated manifold (FGM) approach is proposed and validated by nonpremixed methane jet flames. The effects of radiation and buoyancy were critically examined, and nonpremixed and premixed tabulation methods were compared, revealing the importance of radiation, buoyancy, and appropriate flamelet prototype in accurate FGM modeling.

Development of the TFC turbulent premixed combustion model: the combustion rates and the counter-gradient transport phenomenon [PDF]

open access: yes, 2001
We analyze to “bottlenecks” of turbulent premixed combustion modeling at developed turbulence corresponding to modern lean-premixed large-scale industrial gas-turbine combusters when instantaneous combustion (heat release) takes place in thin strongly ...

Dynamics of Thermoacoustic Oscillations in Swirl Stabilized Combustor without and with Porous Inert Media

open access: yesJournal of Combustion, 2022
Lean premixed (LPM) combustion processes are of increased interest to the gas turbine industry due to their reduction in harmful emissions. These processes are susceptible to thermoacoustic instabilities, which are produced when energy added by an in ...

Synchronization framework for modeling transition to thermoacoustic instability in laminar combustors

open access: yes, 2020
We, herein, present a new model based on the framework of synchronization to describe a thermoacoustic system and capture the multiple bifurcations that such a system undergoes.
