OBJECTIVE
The objective of this Expertise Unit is focused on acquiring the knowledge necessary for modeling and optimizing both the aerohydrodynamic and mechanical performance of rotating machines. This professional objective corresponds to careers in aeronautics, automotive, energy production and conversion, petrochemicals, agri-food, and healthcare. These courses are largely based on the design and control of rotating machinery.
PROGRAM
Module 1: Internal aerohydrodynamics of machines: 26 hours
This module consists of three parts: fluid dynamics, blade grid mechanics applied to the construction of axial machines, and the sizing and performance analysis of centrifugal and helico-centrifugal machines.
After a brief review of the characteristics of viscous flow and two-dimensional boundary layers, this course focuses on the study of grid profiles and the representation of the kinematic properties of flat blade grids. The nominal operation of a grid and a compression stage is then covered in this module. The final part explores in greater depth the kinematics of flow, the characteristics of the machine and the definition of losses, as well as the methodology for sizing centrifugal wheels.
Module 2: Aerohydrodynamics - Application: 20 hours of tutorials
This applied course is dedicated to deepening knowledge
in the design of turbomachinery. It mainly consists of a design office
where internal tools for sizing and analyzing the performance of
pumps and fans are presented to students. Working in pairs, the students
are then guided in the use of these tools to handle cases involving
compression turbomachinery design cases.
Module 3: Modeling energy systems: 3 hours of lectures + 18 hours of tutorials
The content of this course, which uses the Modélica modeling language, is based on a systems approach that takes into account the components of a system and how they are coupled. This course covers the case of a compressible fluid turbomachine and the effects of similarity, namely a gas turbine with all its components, the compressor, the turbine, and the combustion chamber, and their operating limits.
Module 4: Acoustics for Engineers: 15 hours
Acoustic problems, whether hydro or aero, are relatively common in the field of rotating machinery. It is therefore essential that engineers training at UE IFMAT have a minimum level of knowledge taught in this module. This course will therefore cover the following topics: physical characteristics of sound, sound levels, establishing the acoustic wave equation, acoustics in enclosed spaces, silencers, absorbers and diffusers, acoustic quality, acoustic measurements, machine noise, and an introduction to the aeroacoustics of turbomachinery.
Module 5: Design elements and architecture of rotating machines: 9 hours
This module covers the analysis of fluid/mechanical interactions for the mechanical design of the main components in the energy conversion chain. The following topics are covered in this module: thrust balancing, sealing systems, and the static and vibratory mechanical strength of shaft lines and components.
Module 6: Numerical simulation of flows in turbomachinery: 6 hours of lectures + 24 hours of tutorials
This CFD (computational fluid dynamics) module covers the numerical simulation of flows for applied problems involving turbomachinery. This project-based course introduces the fundamental concepts necessary for mastering this engineering tool, such as meshing, numerical resolution methods, boundary conditions, etc. The skills acquired at the end of this course are: defining a problem from a numerical point of view, simulating flows, characterizing a turbomachine, and post-processing the results obtained from CFD calculations.
EVALUATION METHODS
Each module leads to either a test, a mini-project, or practical work that will allow for the validation of the expected learning outcomes
at the end of this unit of expertise.
