Pedagogic informations
Training objectives
The course is dedicated to energy transfer in machines using compressible fluids. The main studied machines are volumetric compressors, steam and gas (or combustion) turbines. For each machine, technology elements and thermodynamic evolutions are presented. For gas and steam turbines, the course explains the thermodynamic cycles associated with energy production facilities, including its components. Students will be able to calculate the features and efficiencies of relatively simple installations and have knowledge and the method for evaluating the performances of more complex energy facilities.
Learning objectives
- Select and size a volumetric compressor for a specific application of compressed gaz
- Read and use a Mollier diagram
- Calculate and analyze a plant including a steam turbine, a gas turbine, or a combined cycle plant
- Calculate the efficiency of an installation
- They will also acquire knowledge of technology and vocabulary concerning the different machines and cycles seen during the courses. Students will have a first view on the use of an analytical and thermodynamic cycles calculations software (Thermoptim).
Learning context
This course complements the course "Energy production/conversion 1" (Majeure Energétique) that focuses on incompressible fluid machines such as pumps or fans. The course uses the basics of compressible fluids flow seen in the Dynamics of real fluids course and is a prerequisite for the course "An Introduction to Pinch Analysis & Process Integration".
