Effect of Spray Models on Flame Formation in the Simulation of n-Dodecane Spray Combustion

Effects of spray characteristics in non-reacting condition on ignition delay and flame in reacting condition were investigated. Three spray models were employed, which are fit to the result of non-reacting experiment in different ways. Ignition delay in reacting condition is affected little by vapor penetration and spray angle in non-reacting condition. Flame lift-off length and flame tip position in reacting condition are strongly affected by initial vapor penetration in non-reacting condition and not affected by vapor penetration at corresponding time in non-reacting condition. Therefore, initial part of vapor penetration is more important than the other part in spray modeling.
