Bartosiewicz Yann;

Language

English

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

Learning outcomes

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

Content

• Chapter 1: characterization of performances of driving engines
• Chapter 2: Steam power cycles (Rankine-Hirn)
• Chapter 3: Gas power cycles (Brayton)
• Chapter 4: Combined gas-steam cycles (CCGT)
• Chapter 5: Combined heat and power cycles (CHP)

Teaching methods

The detailed slides of all lectures will be availble since the very beginning of the course (Moodle). The students are expected to study the slides and the related book (compulsory reference) chapter/sections prior the class. This will allow the professor to focus the inclass lecture on the main learning outcomes of each part and to treat typical exam questions when applicable. Moreover, this will also avoid to waste time for details or uneccessary developments and thus this will allow students to have a clear view on what knowledge is expected for the evaluation. Q&A sessions will be also organized to come back on details or to remedy to any missunderstandings.
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 analyse and improve energy production cycles.

Evaluation methods

THe final evaluation relies on a mixt approach (i) continuous and (ii) in session exam:
(i) Continuous evaluation:

• During the quadrimester, different homeworks, with progessive difficulty, will be required. They will consist in developing models and implementing them in the form of computer codes and to write a calculation note (small report). Those homeworks will be linked each others as thsy will will to tackle basics cycles, to further adding complexities and going more in-depth into the analysis according what has been seen in lectures. An oral presentation of the homeworks will be required at the end of the quadrimester. These reports together with the codes, and oral presentation will make an "homework" mark (/20).
• Moreover, some "quizz" will be also organized in class (closed book) in order to assess the learning outcomes of the previous lectures. Those "quizz" will make a "quizz" mark (/20).

(ii) Exam:

• During the exam session a written exam, closed book, will be organized. Questions will be written in english. This will make an "exam" mark (/20).

The final mark will be calculated as follows:

• Final mark (/20) = MIN(exam (/13) + bonus "quizz" (/2) +  "homework" (/7), 20)
• The "quizz" bonus will depend on the "quizz" mark and will be in the range 0/2 - 2/2
• A failed mark in "quizz"  does not prevent the student to reach the maximum final mark (20/20)

The professor could, in virtue of the article 72  of the general studies and exams rules, propose to the president of jury to refuse the registration of a student who did not give back all "homeworks"  for the exam session.
In case of a second exam session, the same rules apply (the marks for the "homeworks" and "quizz" will be kept). Students who did give back homeworks at the first session will be required to provide their homeworks for the first day of the second session.
