Rankine Cycle Simulation and Analysis at constant Boiler Pressure using Auto-generated Steam Table

This work entails simulation, analysis and establishment

of a relationship between input and output parameters of a reheat-regenerative closed feed rankine cycle, regenerative rankine cycle and conventional rankine cycle with auto-generated steam table in MS excel. The steam table was programmed with some of the in-built functions in MS excel that includes If Statement, Hlook up, Index and Match commands to enable automatic update of enthalpy and entropy values in result computations as input parameters (temperature and pressure) are varied. The result from graphical trends shows that the net work done and plant/cycle efficiency at constant boiler steam pressure are respectively linearly proportional to the steam turbine inlet temperature. A general linear equation was determined which is applicable to all the rankine cycles mentioned.
