La mcanique des fluides est aborde sous deux points de vue, physique et mathmatique. Les bases de la mcanique des milieux continus sont d'abord prsentes en dtail en prcisant les hypothses et approximations qui conduisent aux lois de conservation. Les outils d'analyse des quations gnrales, tude en ordres de grandeurs, analyse adimensionnelle et similitude, permettent ensuite d'introduire les approximations de fluide parfait d'Euler, de fluides visqueux en rgime de Stokes et de la couche limite de Prandtl. Les notions de stabilit des coulements, de turbulence et les coulements compressibles sont ensuite prsents. Les coulements multiphysiques ouvrent des perspectives pour la recherche et le traitement d'applications complexes.

In this book, fluid mechanics is addressed from both physical and mathematical perspectives. As a first step, the basic theory of continuum mechanics is detailed, pointing out the different assumptions and approximations that lead to conservation laws. As a second step, scaling studies, dimensional analysis and similitude of the general equations help to introduce the inviscid Euler fluid approximation, the Stokes approximation of viscous flow and Prandtl's boundary layer approximation. Lastly, the concepts of stability, turbulence and compressible flows are presented. Multiphysics approach of flows will provide readers with deeper insights into basic and applied research on complex processing.
