Schneider Tobias

English

#### Summary

Basic lecture in incompressible fluid mechanics

#### Content

Characteristic quantities of an incompressible flow, hydrostatic, viscous stress, dimensional analysis, Navier-Stoke equations, conservation of mass and momentum in integral and differential form, trajectories and streamlines, Bernoulli's equation, lift and drag of a solid body, theory of reduced scale models, inviscid flows, potential flows, unsteady flows, added mass, vorticity dynamics, introduction to boundary layer concept and of turbulence.

#### Keywords

Incompressible flows, Navier-Stokes equation, lift, drag

#### Learning Prerequisites

##### Recommended courses

• Mechanics of continuous media
• Fluid flow

#### Learning Outcomes

By the end of the course, the student must be able to:
• Master the concepts of mass, energy, and momentum balance, E1
• Formulate the basic flow equations, such as the Navier - Stokes equations , AH17
• Describe simplified governing equations, such as the Bernoulli or potential equations, their domain of validity and apply them in appropriate situations , AH19
• Describe flo w in simple geometries, such as over a flat plate, in a tube, or around a sphere of airfoil , AH11
• Link flow behaviour with non - dimensional pa rameters (e.g. Reynolds and Mach numbers) , AH2
• Understand similarity laws and their use for dimensioning an exper imental testbed , AH 33
• Resolve analytically or numerically the potential flow around an airfoil , AH 25
• Describe the physical differences between laminar and turbulent flows , AH4

#### Transversal skills

• Use a work methodology appropriate to the task.
• Assess one's own level of skill acquisition, and plan their on-going learning goals.
