Compressible flows (ME)

Informations générales

  • ECTS

    ECTS 3

Goal(s)

Provide the theoretical knowledge and practical know-how on compressible flow analysis, using approximation tools (tables and diagrams).
Apply this knowledge and know-how to the study of 1D (nozzle, wind tunnel) and 2D (airfoils, air intakes, jets) problems

Content(s)

- Overview, thermodynamics, speed of sound (2h lecture, 3h exercises)
- 1D flux balance - Stagnation conditions - 1D isentropic diagrams (2h lecture, 3h exercises)
- Variable cross-section ducts (2h lecture, 3h exercises)
- Normal shock - applications to nozzle flows (2h lect., 4h exerc.)
- Choked sonic flow - shock position (2h lect., 2h exerc.)
- Ducts with friction loss or mass-transfer (2h lect.)
- Specific experimental methods (2h lect.)
- 2D potential, characteristic lines (3h lect., 2h exerc.)
- oblique shocks, expansion fan (3h lect., 4h exerc.)

Prerequisites :
- Fluid Mechanics (equations, phenomenology, concepts of boundary layer and potential flow)
- Thermodynamics (perfect gas, kinetic theory of gases)
- Mathematics (vector analysis, partial differential equations)

Test

Partial exam (1h, 25%), Final exam (2h, 75%)
