Thermodynamics is an engineering science that is central to most mechanical engineering applications. This course provides an introduction to the thermodynamic concepts that will be required in following courses and in professional applications. The course provides a background for understanding how energy systems such as engines and refrigerators operate.


CLO-1: Analyze the basic principles of thermodynamics for different engineering components and suggest the improvement in thermodynamic cycles. (C4)
CLO-2: Analyze the appropriate methods for improving the performance of various thermodynamic cycles. (C4)
CLO-3: Design the feasible solutions for power generation and/or Refrigeration while keeping in account environmental, cost, energy and amount of natural resources available. (C6)
CLO-4: Practice the positive attitude and seriousness to carry out research in one of the assigned projects. (A2)
