Suppression characteristics of multi-layer metal wire mesh on premixed methane-air flame propagation
Frontiers in Materials, 2023 Metal wire mesh is widely used in the energy industry for its excellent protective properties as a fire stopping and explosion isolating material. In this study, the suppression characteristics of different layers of metal mesh on the dynamic behavior of

Premixed-flame shapes and polynomials [PDF]
Physica D: Nonlinear Phenomena, 2015 The nonlinear nonlocal Michelson-Sivashinsky equation for isolated crests of unstable flames is studied, using pole-decompositions as starting point. Polynomials encoding the numerically computed 2N flame-slope poles, and auxiliary ones, are found to closely follow a Meixner Pollaczek recurrence; accurate steady crest shapes ensue for N>=3. Squeezed

Flame front geometry in premixed turbulent flames [PDF]
Symposium (International) on Combustion, 1992 Experimental and numerical determinations of flame front curvature and orientation in premixed turbulent flames are presented. The experimental data is obtained from planar, cross sectional images of stagnation point flames at a high Damkohler number (80) and turbulent Reynolds number of 60.

Non-Premixed Filtered Tabulated Chemistry for LES: Evaluation on Sandia Flames D and E
Fuels, 2022 The non-premixed filtered tabulated chemistry for large eddy simulations employs numerical filtering to resolve a thin flame front on practical LES numerical grids. The flame structure is modified to be coherent with the domain discretization.

Numerical Simulation of Premixed Methane–Air Explosion in a Closed Tube with U-Type Obstacles
Energies, 2022 Given the spatial structures and functional requirements, there are a number of different types of obstacles in long and narrow confined spaces that will cause a premixed gas explosion to produce greater overpressure and influence the flame behavior for ...

Instability of lean H2-O2-CO2 premixed flames on a flat burner
Nihon Kikai Gakkai ronbunshu, 2015 Global warming and air pollution mainly caused by emissions of CO2 and NOx are serious problems. We focus on a lean H2-O2 premixed flame because H2-O2 premixed flame emits no CO2 and NOx.
