Advanced gas turbine cycles with water or steam addition (i.e., wet cycles) have attracted much interest in recent years and some commercial systems are available. Because water is added into different points of a gas turbine depending on the methods of water addition, the working fluid of gas turbine has been changed to air-water (humid air) mixture at elevated pressure. Thus, the thermodynamic properties of working fluid are different as conventional gas turbines. Accurate calculation models for thermodynamic properties of air-water mixture are of importance for process simulation, and traceable performance test of turbomachinery and heat exchangers in the wet cycle systems. However, the impacts of thermodynamic properties on the simulation of systems and their components have been overlooked. This paper is to present our study and provide a comprehensive comparison of exiting thermodynamic models of air-water mixtures. Different models including ours have been used to calculate some components including compressor, humidification tower, heat exchanger etc. in wet cycles for investigating the impacts of thermodynamic properties on the system performance. It reveals that a careful selection of thermodynamic property model is crucial for the design of cycles. This paper will provide a useful tool for predicting the performance of the system and design of the wet cycle components and systems.
