An experimental study has been made of the evaporation of a fuel droplet of miscible binary mixture on a heated wall. Primary attention is toward the phenomena which are characteristic of the evaporation of a binary fuel droplet as distinguished from the phenomena for a pure fuel droplet. Fuels tested are the mixture of various couples of normal paraffine hydrocarbons. The results show that two minima and two maxima appear in the lifetime curve. The preferential evaporation of the highly volatile component of the fuel is responsible for the first maximum in the film evaporation region. The increase in the content of the highly volatile component results in the first minimum and maximum shifted toward higher wall temperature, as well as the second minimum and maximum toward lower wall temperature. Four different modes of the droplet evaporation are observed.
