Diffusion flames and diffusion flame-streets in three dimensional micro-channels
Combustion and Flame, 2017Abstract Experiments of non-premixed combustion in micro-channels have exhibited different modes of burning. Typically, a diffusion flame is established along or near the axis of a channel spanning the entire mixing layer. It separates a region of fuel and no oxidiser from a region with only oxidiser. Often, however, a periodic sequence of extinction

Micro-explosion effects in a laminar water-in fuel spray diffusion flame
Combustion Theory and Modelling, 2020In this work, we formulate a simple one-dimensional model as a framework for studying the influence of water-in-fuel emulsions on spray diffusion flames.

Abstract The micro-jet diffusion flame can act as the heat source for the micro power generation systems due to some advantages. The present work investigates the effect of hydrogen addition on the structure and stabilization of micro-jet methane diffusion flame by numerical simulation.

Flame base structures of micro-jet hydrogen/methane diffusion flames
Proceedings of the Combustion Institute, 2017Abstract In this study, a comparison of flame base structures of hydrogen/methane–air diffusion flames formed over a tiny-jet is made numerically for both isothermal and thermal conductive burner conditions, in order to clarify the fuel dependent flame stabilization mechanisms.

Temperature and optimum ionization in the micro diffusion flame
Combustion and Flame, 1983Abstract The simple method previously proposed for estimating the maximum temperature of a diluted micro hydrogen diffusion flame from its composition index has been examined experimentally, using a thermocouple, and has been shown to be satisfactory in certain selected cases.

Numerical Analysis of Micro-Scale Diffusion Flame Structure Using Methane Gas as Fuel
Advances in Thermal Engineering, Manufacturing, and Production Management, 2021Number of numerical analyses are done and we have made a comparison on the microscale flame shape for different methane fuel exit velocity, height, and structure by varying the flow velocities along the domain. These calculated numerical models and analysis results thus created by taking the mathematical model is used to figure out the height of the ...

Development of a micro-flame ionization detector using a diffusion flame
Sensors and Actuators B: Chemical, 2012Abstract A micro-flame ionization detector (micro-FID) design is presented that is targeted for use in a portable gas sensor. Our micro-FID is based on a diffusion flame and features a folded flame structure that is more sensitive than a counter-flow flame designs.

Abstract The micro/mesoscale combustion system of liquid ethanol and the visualization measurement system of flame were designed and constructed on the basis of the microscale combustion theory of liquid fuels. The characteristics of the micro/mesoscale liquid ethanol diffusion flame were investigated experimentally.

Abstract Hydrogen (H2) is considered as a carbon-free alternative fuel. The heat release characteristics of H2 flame as a key parameter in its combustion process are unclear. In this study, the combustion and heat release characteristics of H2/air diffusion flame on a micro-jet array burner were experimentally and numerically investigated.
