Content
- Basic aspects of technical thermodynamics: balance equations of the motive power, ideal gas, properties of gaseous systems, entropic diagrams, simple transformations of state, irreversibilities, work of friction in straight pipes, regular/singular pressure drops.
- Compression and expansion: energy balances, isentropic and polytropic models/efficiencies, compressors, fans, turbines, axial and radial engines, kinematic analysis, characteristics curve of a turbomachinery, of a circuit, working point stability, compressors with intermediate cooling.
- Thermodynamics of vapors: phase change, determination of the state variables, thermodynamic diagrams and tables.
- The humid air: formalism, absolute/relative humidity, dry/wet bulb temperature, Mollier chart, air-water mixtures, humid air mixing
- Introduction to combustion : phenomenology of combustion, balance equation and stoichiometry, coefficients of the quality of combustion, heat of combustion, heating value of fuels, adiabatic combustion temperature, main pollutants produced by the combustion of fuels.
- Gas turbines: calculations of the thermodynamic cycle, optimisation, static applications.
- Power generation with steam: Rankine-Hirn cycle, main components, energy analysis, energy balance over each component, efficiency, physical/thermodynamic constraints, complex cycles including bleeding and reheating
- Refrigeration engines: simple cycle, selection criteria of the thermodynamic fluid, cycle with double compression and double expansion, cascade cycles. The heat pump.
- Practical sessions: they include exercises.
- The pedagogical methods used aim at developing a sound understanding of the physics of the physical phenomena involved and knowledge of the systems which enable to achieve the thermodynamic processes
Teaching methods
Due to the COVID-19 crisis, the information in this section is particularly likely to change.
- Course lectures
- Session of exercises
- Lectures in the classroom or mixed (classrooms with simultaneous broadcasting on Teams) depending on the pandemic conditions
Evaluation methods
Due to the COVID-19 crisis, the information in this section is particularly likely to change.
Written exam consisting of theoretical questions and exercises. The exam is with closed books and notes. The score on the theoretical questions of the exam counts for 50% of the overall score. The score on the exercises of the exam counts for 50% of the overall score.We maintain the right to ask a student for an oral exam in case of technical problems or suspicion of fraude.
