steamy

WIP A python program for modelling simple Rankine cycles or steam systems.

Model a simple steam turbine using Willans Line model and IAPWS-IF97 steam tables.

Modelling parameters taken from Sun and Smith 2015 (Performance Modeling of New and Existing Steam Turbines).

Class turbine.Turbine(**kwargs)

Essential Parameters:

P_1 - Turbine Inlet Pressure (bara)

P_2 - Turbine Outlet Pressure (bara)

T_1 - Turbine Inlet Temperature (degC)

Optional Parameters:

m_act - Actual mass flowrate of steam (kg/s)

m_rat - Ratio of actual to maximum flowrate (kg/kg)

m_max - Maximum flowrate of steam through the turbine (kg/s)

Q - Useful heat content of the outlet stream (kW)

W - Shaft work produced by the turbine (kW)

Dependencies:

• iapws (built using v1.4.1)
• numpi-scipy

To do

• Include more methods
• Create tests for condensing turbine
• Documentation
• Integrate IF97 model
