Project 2 - Rankine cycle Simulator

Aim:

Simulating the Rankine cycle using Xsteam library

Definition:

The Rankine cycle is a model used to predict the performance of steam turbine systems. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing a phase change. It is an idealized cycle in which friction losses in each of the four components are neglected. The heat is supplied externally to a closed loop, which usually uses water as the working fluid.

Schematic and T-s diagram:

Processes:

1-2: Isentropic Expansion in Turbine
2-3: Constant pressure heat rejection in Condensor
3-4: Isentropic Compression in Pump
4-1: Constant pressure heat addition in Boiler

Stepwise Explanation:

1. Printing in the command window about the process and their numbers.
2. Taking input from the user for temperature and pressure at the turbine inlet and pressure at condenser inlet.
3. Using XSteam library and state equations to calculate pressure, temperature, enthalpy, and entropy at each state point. XSteam is similar to a steam table.
4. Calculate the Turbine, Pump, and Net-work; Thermal efficiency; and Steam rate
5. Plotting the T-s and h-s diagrams

Results:
