A research on the gas turbine performance in the condition of fault based on the second law of thermodynamics

This paper analyzed the gas turbine performance in the condition of fault by using the thrust work potential transferfunction,as a figure of merit of the work potential which based on the second law of thermodynamics.Contrasted against the delta of thecomponent efficiencies,the delta of the thrust work potential transfer function in some typical fault is derived.The result was suggested that the thrust work potential transfer function can express the gas turbine performance wonderfully in the point of view of the transfer the stored energy in fuel into useful thrust work,This is the groundwork for the further study the capability of the gas turbine which in the condition of all kinds of faults.
