This article describes recent progress on premixed flame dynamics interacting with acoustic
waves. Expressions are derived to determine the stability of combustors with respect to …

With a growing need for replacing fossil fuels with cleaner alternatives, hydrogen has
emerged as a viable candidate for providing heat and power. However, stable and safe …

An air jet cooling method is adopted to reduce the temperature of the trailing edge wall of a
bluff-body flameholder. The added cooling air jets would rebuild the flow field and reduce …

The laminar flame dynamics of the methane-air premixed mixture are investigated
experimentally in a preheated micro combustor with a flame holder which can act as a micro …

The lean premixed combustion LPC can achieve clean combustion of natural gas and
reduce emissions of harmful gases. However, this combustion mode is usually difficult to …

In a previous study, we fabricated a well-designed mesoscale combustor with a flame holder
and preheating channels to improve the flame stability under extreme combustion …

The bluff-body is widely employed to improve the performance of the lean premixed
combustion LPC which has advantages of high efficiency and low pollutant emissions. To …

To achieve cleaner emissions, the ultra-lean premixed flames of 80% H 2–20% CH 4–air
with the coupling effect of flow and heat recirculation were experimentally investigated. The …

Large eddy simulations (LES) of combustion instabilities are often performed with simplified
thermal wall boundary conditions, typically adiabatic walls. However, wall temperatures …

The response of a premixed flame subjected to either flame stretch (and associated Lewis
number effects) or heat loss has been well documented in the literature and has enabled a …
