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 code to simulate a complex power cycle under different conditions and performing energy/exergy analysis

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

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

Lectures are physically (comodal or full e-lecture to comply with any change in the sanitary rules) given according an hybrid apporach: (i) Students are asked to read and study the content of the next course; (ii) during the first hour, the Professor gives a synthesis of the main points; (iii) during the second hour a strong interactivity between students and professor will be expected by Q&A and discussions. 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

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

Project:Simulation of  (i) a complex Rankine Cycle including breedings and reheat, (ii) a gaz turbine cycle, (iii) a combined cycle. The project can cover all or partly those cycles. The project also includes the energy and exergy analysis of those cycles.
Exam: Closed book (3h). Understanding/theory/application. The Professor might proceed to a further oral exam for any student being involved in a technical issue or supected of fraud during the written exam.
The final mak is calculated according the project and the exam marks. The relative weights of the project and exam is variable and calculated according the marks obtained in both evaluations. The exact calculation key is presented at the first lecture and in the moodle site (starting slides of the course).  Quick tests could be done during the session. Those tests could be considered as trainings as well as certifications which will be then integrated into the final mark according a variable weights.
