【Abstract】 The working fluid during HAT and STIG cycles is referred to as "moist combustion gas" and it contains a large amount of steam and is considered as a real gas in this thesis. The state equation has been established for the moist combustion gas as a two terms Virial equation. With the aid of the state equation and the deviation function, the thermodynamic properties of moist combustion gas can be calculated accurately. The method can be used to calculate the thermodynamic properties of the moist combustion gas for any kind of hydrocarbon fuel, any steam injection ratio and any fuel coefficient.更多还原
