Wind tunnel evaporation experiments are made to study the kinetics of evaporation of a complex hydrocarbon mixture: kerosene, and of binary and ternary mixtures of n-C7, n-C8 and n-C9. The theoretical model used is based on a mass transfer coefficient approach. For a complex mixture the use of hypothetical components is adopted. Properties of the pseudo-components are defined using a characterization procedure. The model is found to be in very good agreement with experimental data. Specific recommendations are given for further investigations on oil and oil fractions evaporation.
