A two-dimensional numerical simulation is applied for spray flames formed in a laminar counterflow, and soot formation behavior is studied in detail. N-decane (C_<10>H_<22>) is used as a liquid fuel. A one-step global reaction is employed for the combustion reaction model. A kinetically based soot model with flamelet model is employed to predict soot formation. Radiation is taken into account using the discrete ordinate method. The results show that the soot is formed mainly in the spray diffusion flame region. The soot formation behavior is well demonstrated by the present soot formation model.
