Gas premixed combustion at high turbulence. Turbulent flame closure combustion model [PDF]
Experimental Thermal and Fluid Science, 2000 Abstract This paper is devoted to analyze the special class of turbulent premixed flames that we call intermediate steady propagation (ISP) flames. These flames are common to industrial premixed combustion chambers which operate at intensive turbulence when velocity pulsations are significantly higher than the flamelet combustion velocity.

Numerical investigation of the premixed V-flame stabilization and blowout [PDF]
مهندسی مکانیک شریف, 2021 Global warming and high fossil fuel consumption increase the application of the low-Nox burner with lean-premixed combustion. However, this type of combustion is more susceptible to thermoacoustic instabilities.

DNS for Turbulent Premixed Combustion
, 2021 Most of practical combustion occurs in turbulent flows which involve strong coupling between turbulence and chemical processes. The heat release from combustion alters the fluid properties such as density and viscosity and in turns affects the turbulence.

Computations of a Bluff-Body Stabilised Premixed Flames Using ERN Method
ChemEngineering, 2022 Combustible carbon-based energy is still prevailing as the world’s leading energy due to its high energy density. However, the oxidation of these hydrocarbons disturbs the natural carbon cycle greatly by increasing greenhouse gases.
