Structure and Laminar Flame Speed of an Ammonia/Methane/Air Premixed Flame under Varying Pressure and Equivalence Ratio. [PDF]
Energy Fuels, 2021 This paper presents a joint experimental and numerical study on premixed laminar ammonia/methane/air flames, aiming to characterize the flame structures and NO formation and determine the laminar flame speed under different pressure, equivalence ratio ...

Large Eddy Simulation of a Bluff Body Stabilised Premixed Flame Using Flamelets. [PDF]
Flow Turbul Combust, 2018 Large Eddy Simulations of an unconfined turbulent lean premixed flame, which is stabilised behind a bluff body, are conducted using unstrained flamelets as the sub-grid scale combustion closure.

Comparison of the Reactive Scalar Gradient Evolution between Homogeneous MILD Combustion and Premixed Turbulent Flames [PDF]
Energies, 2021 Moderate or intense low-oxygen dilution (MILD) combustion is a novel combustion technique that can simultaneously improve thermal efficiency and reduce emissions.

Turbulence–flame interactions in lean premixed dodecane flames [PDF]
Proceedings of the Combustion Institute, 2017 Turbulent lean premixed dodecane/air flames are simulated in a doubly-periodic domain using detailed kinetics and transport over a range of Karlovitz number. We observe extensive thickening of thermal profiles through the flames that increases with turbulent intensity.

Numerical studies of the interaction mechanism between the pilot flame and main flame [PDF]
E3S Web of Conferences, 2022 The interaction mechanism between the rich premixed pilot flame and lean premixed main flame was investigate in this paper. A two-dimensional numerical model was adopted with detailed chemistry and species transport and with no artificial flame anchoring

Non-Premixed Filtered Tabulated Chemistry: Filtered Flame Modeling of Diffusion Flames
Fuels, 2021 The flame front filtering is a well-known strategy in turbulent premixed combustion. An extension of this approach for the non-premixed combustion context has been proposed by means of directly filtering counterflow diffusion flamelets. Promising results

Original scale simulation of gas explosion at heading face in coal mines
Meikuang Anquan, 2023 To study the propagation of gas explosion shock wave and flame in coal mine heading face at real scale, the numerical simulation software of gas explosion was used to establish roadway models of different scales, and the influence of premixed gas ...
