Abstract
Current studies of multicomponent droplet evaporation do not successfully capture the evaporation characteristics of fuel blends. Reasons for this are the usage of averaged properties of fuel-components and the lack of data for physical properties of fuel components-especially for cycloparaffins and substituted aromatics which form a significant portion of the mixture. We present an approach based solely on functional groups that are present in the components of the fuel. In the description of the multicomponent evaporation, we incorporate a non-ideal evaporation formulation while still providing computationally efficient calculations. This allows the evaluation of evaporation and combustion characteristics of virtually any fuel blend based only on the intrinsic primary and secondary functional groups. Studies of various fuel blends and surrogates, including Jet-A, JP-8 and gasoline are performed and results are compared against experimental data. Due to the generalized nature of this approach, the proposed method provides an effective alternative for existing computational techniques dedicated to multicomponent droplet evaporation; further work involving the utilization of this approach in various combustion codes can be performed.
