| Course objective : | This course establishes a link between general courses in maths, physics, thermodynamics, numerical analysis, etc., and a particular domain of engineering sciences: fluid mechanics. It has a double objective:
* to teach students to use the notions studied in these general courses in order to approach a new discipline, which involves "crossing" these notions and developing a synthetic and applied approach
* to provide students with the bases in fluid mechanics and to teach them to apply them to a number of concrete cases.
For engineering students who are going to specialise in the domains of construction, geology, mechanics, aeronautics, and applied physics, this course will serve as a foundation for a series of more specialised courses such Fluid Mechanics, Hydraulics, Applied and Environmental Hydraulics, Hydrogeology, the study of Pumps and Turbines, Hemodynamics, etc.
For the others, this course is about training future engineers in a scientific approach while providing the "basic vocabulary" that will allow them to interact with specialists.
Particular attention is paid to fluid resistance, flows in pipes in continuous and discontinuous movements, the flow of a perfect gas and to applications of the theory of quantities of movement and the momentum theory. |
