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.

Experimental and numerical study of the accuracy of flame-speed measurements for methane/air combustion in a slot burner [PDF]
, 2011 Measuring the velocities of premixed laminar flames with precision remains a controversial issue in the combustion community. This paper studies the accuracy of such measurements in two-dimensional slot burners and shows that while methane/air flame ...

Vectorial structure of the near-wall premixed flame
Physical Review Fluids, 2019 A turbulent premixed flame anchored by a solid wall can reach a statistically stationary state. Overall the configuration is counterflowlike. Flame-wall interactions under such conditions are key to understanding combustion in a confined space and in ...

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 ...
