Grahic Jump Location
Minimum pressure, required for an n-heptane fuel droplet to attain a critical mixing state, plotted as a function of ambient temperature
Grahic Jump Location
Mole fraction of n-heptane predicted by PR, SRK, and RK-EOS for an n-heptane-nitrogen system in thermodynamic equilibrium at four different pressures. Pr is the reduced pressure normalized by the critical pressure of pure n-heptane. The experimental data from Chung et al. 23, for Pr=2.5 and 5.0, are also included in the plots.
Grahic Jump Location
(a) Phase equilibrium in terms of the pressure-temperature diagram and (b) latent heat of vaporization of n-heptane versus temperature for n-heptane-nitrogen system in thermodynamic equilibrium, as predicted by PR, SRK, and RK-EOS at three different pressures. See Fig. 1 for additional details.
Grahic Jump Location
Non-dimensional droplet lifetime, predicted by PR, SRK, and RK-EOS, plotted versus pressure at three different ambient temperatures
Grahic Jump Location
Final temperature and fuel vapor mass fraction at the droplet surface plotted as functions of pressure. The ambient temperature (Ta) is 1000 K, and initial droplet temperature (To) 300 K. The final time corresponds to a time when (d/do)2=0.2.
Grahic Jump Location
(a) Comparison between the predictions using PR, SRK, and RK-EOS and the measured data of Nomura et al. 21 at P=5 atm and Ta=655 K. (b) comparison between the predictions using PR, SRK, and RK-EOS and the measured data of Nomura et al. 21 at P=50 atm and Ta=453 K.
