Simulation of heat transfer of mildly-cracked n-decane in a tube with 3-dimensional equation of state look-up table

摘要

The objective of this paper is to develop a numerical method to simulate mildly cracked fuel flow and heat transfer at supercritical pressures. The thermodynamic and transport properties determined by temperature, pressure, and mass fraction of each component were simplified to the function of temperature, pressure and conversion rate. These properties were reconstructed by a three-dimensional equation of state (EOS) look-up table. The three-dimensional EOS table look-up method was two orders of magnitude faster than SUPERTRAPP database. This method was validated and could improve the efficiency of design for active cooling system of scramjet engine.
