Abstract

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. Decane and heptane are targeted as a fuel. The results show that for both fuels, temperature and mass fractions of chemical species cannot be clearly identified by mixture fraction and scalar dissipation rate by themselves. This behavior is caused by the fuels' evaporation in the spray flame, and becomes marked in the smaller droplet size condition due to its higher evaporation rate and in the higher equilvalence ratio condition due to its larger evaporation amount.
