Course content

Dimensional analysis and similarity. One-dimensional compressible flows in pipes and nozzles. Critical condition and choling. Normal shocks. Two-dimensional compressible flows. Oblique shocks. Prandtl-Meyer expansion. Open channels flows. Optimum cross section. Critical flow and hydraulic jumps. Basic theries for hydraulic machines.

Learning outcome

The course provides the student with knowledge about:
- Similarity and dimensional analysis
- Compressibility effects
- One and two-dimensional gas dynamics
- Shocks and expansion waves
- Flows in open channels
- Hydraulic jumps
- Introduction to hydraulic machines

The course gives the student knowledge about:
- Problems associated with compressibility effects
- Flows with free surfaces
- Basic knowledge of hydraulic pumps and turbines

Skills:
The course should enable the student to:
- Calculate compressible flows in ducts and nozzles
- Calculate flows with shocks and expansion waves both in ducts and for immersed bodies
- Calculate the flow in open channels where the shape and inclination varies along the flow
- Calculate losses associated with hydraulic jumps
- Perform calculations of the main geometry and performance of pumps and turbines

General competence:
The course should give the student:
- When the student has finished the course, he/she shall have general knowledge about gas dynamics and channel flows where discontinuities may exist
- The student will also have a fundamental understanding of the transfer of forces between the fluid and a rotating machine

Learning methods and activities
