ABSTRACT
Power cycles are often classified by the character of the working fluid in the cycle. The two general classes of cycle are the vapor cycle and the gas cycle. The energy for the heating and vaporizing of the liquid is provided by the combustion of a fuel sources in the boiler or using an external energy to generate superheated steam. The vapor leaves the steam generator and is expanded isentropically in a prime mover to provide the work output of the cycle. The presence of moisture in the turbine can lead to mechanical difficulties such as excessive erosion of the turbine blades. The effort required to obtain the necessary properties is greatly reduced by the use of the computer-generated values. The type efficiency is defined as the ratio of the ideal thermal efficiency of a given cycle divided by the efficiency of a Carnot cycle operating between the same maximum and minimum temperature limits.
