Abstract

This work numerically studies the evaporation characteristics of 6 typical gas turbine fuels (JP-4, JP-5, JP-7, RT, Jet A-1, and TS-1, respectively). In this work, the influence of ambient temperature and liquid properties on the droplet lifetime is examined. At the same initial conditions (e.g. fuel temperature Ts0 = 300 K, droplet diameter D0 = 1 mm and atmospheric pressure p = 101.33 kPa) and low ambient temperature (e.g. 500 K), significant differences in evaporation characteristics among these fuels are observed. JP-4 has the longest droplet lifetime while JP-7’s is the shortest. However, at high ambient temperature (e.g. 2000 K), the droplet lifetimes of the fuels are almost identical. Under critical temperature, it is shown that the fuel properties remarkably impact the evaporation rate.
