Heat conduction controlled combustion for scramjet applications [PDF]

The use of heat conduction flame generated in a premixed supersonic stream is discussed. It is shown that the flame is controlled initially by heat conduction and then by chemical reaction.

Impact of low-pressure conditions on flame width and volume of buoyant methane laminar diffusion flames

Case Studies in Thermal Engineering
In this work, an experimental investigation of the main morphological parameters of buoyant methane laminar diffusion flames, including flame width and flame volume, is carried out under various sub-pressures (20-100 kPa).

Analysis and Comparison of Large Time Front Speeds in Turbulent Combustion Models [PDF]

, 2011
Predicting turbulent flame speed (the large time front speed) is a fundamental problem in turbulent combustion theory. Several models have been proposed to study the turbulent flame speed, such as the G-equations, the F-equations (Majda-Souganidis model)

Choice of reaction progress variable under preferential diffusion effects in turbulent syngas combustion based on detailed chemistry direct numerical simulations

Scientific Reports
The combustion of hydrogen and carbon-monoxide mixtures, so-called syngas, plays an increasingly important role in the safety context of non-fossil energy generation, more specifically in the risk management of incidents in process engineering plants for
