This paper examines the effects of energy exchange between droplets and the gaseous phase as well as latent heat on evaporative cooling effects due to droplet group combustion. In addition, a parcel model on numerical simulations of spray combustion is investigated. Two-dimensional direct numerical simulations of spray flames in a laminar counter flow are employed. The results show that the contribution of evaporated vapor enthalpy has the strongest influence on the energy exchange and the latent heat causes the reduction of gaseous temperature in the droplet group flame. Furthermore, the use of the parcel model has the risk of causing a delay in the combustion reaction since the partial fuel vapor pressure increases at limited locations, which suppresses the global droplet evaporation rate.
