Engineering thermodynamics

Presentation

Programme (detailed contents):

The laws of thermodynamics and their consequences. Physical meaning of irreversibility, degraded work and production of entropy. Energy balances for open systems and consequences. Relationship of Barre St Venant. Relationship of Bernoulli. Entropy balances for open systems. Exergy balances for open systems and physical meaning of exergy. Gibbs free energy and chemical component of exergy. Irreversible evolution of fluids. Isentropic and polytropic efficiencies. Analysis of turbines and compressors performance. Energy management. Energy-based and exergy-based prices of energy. Thermo-economic optimization of industrial systems.

 

Organization:

The basic concepts are introduced and discussed during lectures. Then, tutorial sessions allow to illustrate and implement the concepts presented formerly. The positive attitude of the student is systematically sought and promoted by an organization that makes a privileged place to attendance and to active participation. A series of frame-type problems guides the individual work of students.

Objectives

At the end of this module, the student will have acquired the theoretical concepts for analyzing the performance of thermodynamic systems in terms of energy (first law) and exergy (taking into account both the 1st and the 2nd law. He will be able to explain the difference between energy and exergy (or mechanized energy).

 

He will be able to implement these concepts to analyze the performance (quantity and quality of energy used or produced) of complex industrial facilities.

 

He will be aware of the existence of methods for studying the profitability of an investment to save energy and of methods for energetical optimization of industrial plants.

Needed prerequisite

Unit “Thermodynamics : fundamentals and application to phases equilibria” (# I1BETH11) of the INSA second year curriculum or equivalent.

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
