Numerical Analysis of Micro-Scale Diffusion Flame Structure Using Methane Gas as Fuel
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 ...

Experimental Studies of the Micro-Structures of Opposed Flow Diffusion Flames: Methane
Combustion Science and Technology, 1997Abstract The micro-structure of an atmospheric pressure, opposed flow, methane diffusion flame has been studied using heated micro-probe sampling. Mole fraction profiles of major products as well as trace aromatic, substituted aromatic, and polycyclic aromatic hydrocarbons (PAH up to C16H10, e.g., pyrene)were quantified by direct gas chromatography ...

The estimation of the temperature of a dilute micro hydrogen-air diffusion flame
Combustion and Flame, 1970A method is proposed for estimating the “temperature” of a micro hydrogen-air diffusion flame on the basis of the hydrogen content of the unburnt gas mixture. It assumes that the flame, being small, behaves as a prernixed flame, composed of hydrogen and oxygen in stoichiometric proportions diluted by nitrogen; the composition is expressed in terms of a

An experimental study is conducted on a laminar diffusion flame established over a 50 mm x 50 mm x 10 mm slab of PMMA subject to a forced oxidizer flow parallel to the surface. The parameters varied are the oxygen concentration, the forced flow velociry and the length of pyrolyzing fuel.

In this study, a set of experiments were carried out in micro- and normal gravities to study the flame shape and oscillation of co-flow laminar diffusion ethylene and propane flames. The experimental results show that in microgravity, the flame length and width are larger than those under normal gravity, and the ratio of flame length to width is lower ...

Composition, temperature, and ionization in the micro hydrogen-air diffusion flame
Combustion and Flame, 1983Abstract Characteristic features of the ionization of hydrocarbons in the micro hydrogen-air diffusion flame are discussed in terms of the temperature of the flame. The constant diluent-fuel ratio for optimal ionization is shown to be related to the flame temperature. A modified rate coefficient is proposed for the ionization step, CH + O → CHO

Proceedings of the Combustion Institute, 2007
Abstract Heating, gasifying and burning processes of a micro plastic-resin particle, which has a diameter of about 200 μm and is suddenly exposed to a hot oxidizing atmosphere, are observed and optically processed by combining a micro schlieren system with a high-speed CCD video camera.

Evaporating Interface in a Capillary Tube With High Heat Flux Induced by Micro Diffusion Flame
Heat Transfer: Volume 3, 2008A series of experiments was conducted to understand the combustion characteristics and evaporating interface behavior of liquid fuel in capillary tubes. The flame shape, interface location of fuel front and tube outer surface temperature was visually observed and measured using CCD and IR camera, respectively.
