Abstract : An experimental/computational approach to model precombustion chemistry and transport behavior for hydrocarbon fuels under supercritical conditions was developed. Models for the computation of thermophysical properties of real fluids were incorporated into a general purpose computational fluid dynamics (CFD) code. The models were applied to analyze heat transfer in supercritical fluids over a range of flow conditions from the laminar to turbulent regimes. The effects of turbulence and buoyancy were studied in detail. Advanced thermal stability models for jet fuels were incorporated into the code. Model predictions were compared with deposition data in the literature and with a concurrent experimental study. Experiments were performed at the University of Iowa and at Wright Laboratory using jet fuels and sulfur hexafluoride.
