Many experimental studies have been conducted to reduce soot in diesel engine, gas turbine and combustor using liquid fuel over a long period of time. However, these studies treated spary combustion only in mactoscopic point of view. Therefore, the effects of combustion conditions, such as, droplet number density, combustion chamber temperature distribution etc., on soot formation and oxidation process are not sufficiently known yet.
In this experimental study, the data concerned with the soot formation and oxidation from the combustion of free fuel droplet array ejected into high temperature air stream are obtained by two color method, aiming to show the effects of ambient temperature, droplet spacing and cetane number etc.. From this experimental study, the effects of temperature of ambient gas, droplet flame, dropler diameter, cetane number on the soot formation and oxidation mechanism are discussed.
