PyRankine

The step-by-step codes of the rankine cycle simulator from zero abstraction to the general abstraction are provided in the PyRankine.

We wish that the PyRankine may be a helpful vehicle for you to understand Computational Thinking and improve the programming skills.

The Example Rankine Cycles used in the follow codes are from Michael J. Moran. Fundamentals of Engineering Thermodynamics(7th Edition)

• step 0 : Zero Abstraction of The Ideal Rankine Cycle(Example 8.1)

  The simple data types and expression only 
  

• step 1 : The Simple Abstraction of The Rankine Cycle(Example 8.1，8.2)

  Structure data types(List,Dict) and functions
  

• step 2 : The Simple Object-Orientation Abstraction of The Ideal Rankine Cycle(Example 8.1)

  Object-oriented programming
  

• step 3 : Object-Orientation Abstraction and JSON Textual Representation of The Ideal Rankine Cycle(Example 8.1)
