Characteristics of flamelet in spray flames in a laminar counterflow are investigated by a two-dimensional DNS in terms of mixture fraction and scalar dissipation rate. The motion of spray droplets is calculated by the Lagrangian method without parcel model. The results show that large difference in the trends of temperature and mass fractions of chemical species in mixture fraction space between the spray flame and gaseous diffusion flame is observed. Especially the temperature in the spray flame is much higher than that in the gaseous diffusion flame. This is considered due to much lower scalar dissipation rate and co-existence of premixed and diffusion combustion in the spray flame. It is also revealed that for the spray flame, temperature and mass fractions of chemical species cannot be clearly identified by the mixture fraction and the scalar dissipation rate by themselves. The behavior becomes marked in lower strain rate conditions.
