  The present work aims to investigate the complex phenomena occurring during
high-pressure/high-temperature fuel injection of the Engine Combustion Network
(ECN) Spray-A case. While commonly in the literature transcritical mixing cases
are approached using traditional cubic equation-of-state models, such models
can prove insufficient in the accurate prediction of liquid density and speed
of sound. The purpose of the present investigation is to employ a general
tabulated approach which can be applied to any type of thermodynamic closure.
At the same time, a more advanced model based on the Perturbed-Chain
Statistical Associating Fluid Theory (PC-SAFT) is employed to create the
thermodynamic table, as it is proven superior to the traditional cubic models,
while also having the capacity of predicting Vapor-Liquid-Equilibrium. The
model has been used for a combination of dodecane and nitrogen mixing,
corresponding to the well known Spray-A conditions. Vapor penetration and
mixing both in terms of temperature and mass fraction are found in agreement to
experiments, within the experimental errors. Also, the thermodynamic states
correspond well with the adiabatic isobaric-mixing curve, demonstrating the
energy-conservative nature of the approach.
