A state-of-the-art micro-mixing micro-combustor with enhanced flame stabilization characteristics using H2-air mixtures

Energy Conversion and Management: X
A novel micro-mixing micro-combustor was developed and the flame stabilization characteristics were investigated numerically. The Combustor exhibited excellent lean stability limits, with stability limits increasing as the fuel–air mixture became leaner.

Asymmetric hydrogen flame in a heated micro-channel: Role of Darrieus–Landau and thermal-diffusive instabilities [PDF]

International Journal of Hydrogen Energy, 2016
Present work examines numerically the asymmetric behavior of hydrogen/air flame in a micro-channel subjected to a non-uniform wall temperature distribution. A high resolution (with cell size of 25 μm × 25 μm) of two-dimensional transient Navier–Stokes simulation is conducted in the low-Mach number formulation using detailed chemistry evolving 9 ...
