Counterflow Combustion of Micro Organic Particles

Clouds combustion have been published over the last few years; see, for of the article on flame propagation through micro-organic dust parti clesbut from the fact that in many practical applications the flow field is to yield realistic flame prediction under such conditions, counterflow suitable for studying these cases.over the last few decades, the counterflow extensively adopted in theoretical, experimental and numerical studies as a various physical effects on real flames on real flames, such as stretch, radiation and chemical kinetics (daou, 2011), (thatcher et al.) and (wang et studies are done for gaseous fuels. eckhoff clarified the differences and dust and gases (eckhof, 2006). it has been concluded that there are two b asicdusts and gases which are of substantially greater significance in design of these similarities. firstly, the physics of generation and up-keeping of dust gas/vapor clouds are substantially different. secondly, contrary to premixed the propagation of flames in dust/air mixtures is not limited to the concentration range of dynamic clouds. thus here we modeled counterflow clouds and the effect of lewis number on gaseous fuel mass fraction investigated. for describing a one dimensional, axisymmetric, premixed flame in a configuration. uniformly distributed volatile fuel particles in air are considered as the initial number density of the particles, (number of particles per unit radius are presumed to be known. vproduct [p] is assumed. the flame position is determined andthe effect of lewis number change on the gaseous fuel mass fraction distribution is investigated.
