“…The present results are validated against ref. (Chung and Kawaguchi 1995) where the evaporation of d 0 = 200 μm n-heptane droplets is investigated using a drop tower. The velocity of the droplets and the air stream are almost equal, thus the reported value of Re is 0.3.…”

Advanced gas turbine and internal combustion engine combustion chambers operate at highly elevated pressures and temperatures. Therefore, spray vaporization analysis cannot be limited to the atmospheric environment since evaporation strongly depends on ambient conditions. Presently, the effect of air pressure and temperature on droplet evaporation rate was investigated by using both a transient and a steady-state approach. A corresponding states model was derived for the steady-state evaporation rate for n-alkanes in the range of C2–C9 with an excellent fit quality and < 1% model uncertainty, considering the thermophysical data uncertainties. The model was tested for C1, C10, and C12 n-alkanes as well with low success. The ambient conditions were evaluated in terms of reduced pressures and temperatures, covering the range of 0.02–0.5 and 1.2–1.5, respectively. However, the applicability of the model was limited to reduced temperature of 1.3–1.5, as higher discrepancy was observed between the trends of the different n-alkanes at lower temperatures. Since the heat-up phase of practical sprays in combustion chambers is often short, the present model might significantly reduce the computational effort required for liquid evaporation calculations.

A model for sphericosymmetric thin‐flame combustion of multicomponent fuel droplets has been developed in the first part of this two‐part work. The model incorporates effects of droplet surface regression and gas‐phase Lewis number. It is observed that both these effects affect the results substantially. The study also reveals the transient nature of the combustion process. Copyright © 1999 John Wiley and Sons, Ltd.
