On Surrogate Fuel Formulation

Calculations of evaporation characteristics (distillation curve, two-phase diagram, critical points) of surrogates are described in detail. The efficiency of some surrogate blends, represented in literature, in reflecting the evaporation characteristics was analysed. Based on the analysis, the chemical capabilities of surrogate models are not linked to their abilities to reflect the phase equilibrium properties of real fuel. It is shown, that blending of pure hydrocarbons must begin with the phase equilibrium and distillation curve calculations. A surrogate mixture was selected which closely matches the boiling-point curve and two phase diagram for Jet-A.Copyright © 2009 by ASME
