AbstractBased upon equilibrium thermodynamics, the differential equations of quasi-1D steady flow were formulated for arbitrary equation of state to study dense gas behavior of hydrocarbon fuels. A complete set of dimensionless numbers to characterize the quasi-1D dense gas dynamics is identified, classified and discussed. A new numerical method based on conservation laws is proposed to study isentropic flow and shock wave of dense gas and applied to flows of n-dodecane. Furthermore, temperature dependence of supercritical kerosene jet structure is partially interpreted by Prandtl-Meyer expansion of dense gas. It is also proved that the maximum momentum flux at the outlet of a nozzle can be achieved at Mach number √2 for isentropic flow of arbitrary fluid.
