Prerequisites
Students are expected to master the following skills: basics in thermodynamics and fluid mechanics , as they are covered within the courses LMECA1855 and LMECA1321
Aims

At the end of this learning unit, the student is able to :

1

In consideration of the reference table AA of the program "Masters degree in Mechanical Engineering", this course contributes to the development, to the acquisition and to the evaluation of the following experiences of learning:

  • AA1.1, AA1.2, AA1.3
  • AA2.1, AA2.2, AA2.3, AA2.4
  • AA3.1, AA3.2, AA3.3
  • AA4.1, AA4.2, AA4.3, AA4.4
  • AA5.1, AA5.3, AA5.4, AA5.5, AA5.6
  • AA6.3

The student will acquire the necessary knowledge to understand, design and evaluate thermodynamic systems involved in power cycles. A the end of the course he/she will be able to:

  • Use the concept of exergy to evaluate the performance of a power cycle and complete the energy approach
  • To formulate a detailed analysis of losses and irreversibilities at each component of a power cycle and present results by plots/pie charts
  • To elaborate assumptions and setup models to simulate a steam, gas and combined cycles
  • To setup a user friendly software with a GUI to simulate a complex combined cycle up to 3 pressure levels and performing energy/exergy analysis
 

The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled “Programmes/courses offering this Teaching Unit”.
Content
  • Chapter 1: characterization of performances of driving engines
  • Chapter 2: Steam power cycles (Rnakine-Hirn)
  • Chapter 3: Gas power cycles (Brayton)
  • Chapter 4: Combined gas-steam cycles
  • Chapter 5: Combined heat and power cycles (CHP)
Teaching methods
Lectures intensively use slides with technical drawings, plots, and main formula. Some theoretical developments and thermodynamic reminders are done in class. Attendance is highly recommended as a permanent link between models/theory/formula and practical/technological arrangements is explained during the class. The spirit of the course is a permanent comparison between the classical energy approach and the exergy analysis.
To apply the theory as seen in class, a project is organized over the whole session with periodic consultations by the assistant
Evaluation methods
Project:Simulation of  (i) a complex Rankine Cycle including breedings and reheat, (ii) a gaz turbine cycle, (iii) a combined cycle. The project also includes the energy and exergy analysis of those cycles.
Exam: Closed book (3-4 h). Understanding/theory/application
Final Mark = 0,4*Mark(project)+0,6*Mark(exam) if Mark(project) and Mark(Exam) >= 10/20
Final Mark = SQRT(Mark(project)*Mark(exam)) if Mark(project)=< 10/20 and Mark(Exam) >= 10/20
Final Mark =MIN(Mark(project),Mark(exam)) otherwise
