In this work, a simple numerical model of the evaporation process of a single droplet of various fuel, e.g., n-alkanes (n-decane, n-hexane, and n-heptane) and kerosene is evaluated with various correlations a standard pressure (0.1 MPa) and various uniform temperature fields. The effect of natural, forced or combined convection is explored using an effective Reynolds number (Re-eff). Studies are performed for n-alkanes and kerosene droplets and have been compared with the empirical data available in the literature for the temporal variation of droplet diameter, droplet surface temperature, and average evaporation rate constants at various temperatures under free-stream and quiescent conditions. A good match is observed for a particular property rule (Eq. 10), with different convective correlations, depending on the convective conditions present.
