چکیده
|
Organic dust ames deal with a eld of science in which many complicatedphenomena like pyrolysis or devolatization of solid particles and the combustion of volatileand char particles take place. one-dimensional ame propagation in the cloud of a fuelmixture has been analyzed, in which the ame structure is divided into three zones: preheatzone, reaction zone and post ame zone. it is assumed that particles pyrolyze rst to yielda fuel mixture consisting of gaseous and charry fuel. in this research, the e ect of charcontent on the pyrolysis process has been taken into account and a novel non-linear burningvelocity correlation is obtained. our results are in reasonable agreement with experimentaldata.
