Tables of the Thermodynamic Properties of Air and the Exhaust Gas from a Turbine Engine
A set of tables is presented that contain several thermodynamic properties of air and the exhaust gas from a turbine engine. The tables were assembled to provide a readily available source of thermodynamic properties routinely used in hand calculations of turbine engine data. The properties include enthalpy, entropy, and specific heat at constant pressure. The properties were calculated using an air com- position from Ref. 1 but modified to reduce the number of constituents to five for reduced computer calculation time. The composition used in these calculations is given as follows:
The molecular weight for this composition was defined as 28. 9646. to represent the J P -4 grade of fuel currently in use in turbine engines. The fuel composition was defined as CnH1. 95n The range of air properties is from 300 to 18000 R, and the pressure range is from O. 5 to 600 psia. The data are tabulated in temperature increments of IOOR and graduated pressure steps of O. 5 to 100 psia. The data for exhaust gas ranges from a temperature of 600 to 40000R, from a pressure of O. 5 to 600 psia, and a fuel-to-air ratio of O. 005 to O. 067. The temperature increments are for enthalpy and 1000R for entropy and specific heat. The properties were calculated using the method of Ref. 2. The thermodynamic properties of the constituent gases were taken from Ref. 3 (argon and neon properties were taken from Ref. 4). Real gas effects were included in the calculation of the air properties
