The course provides basic knowledge on steady and unsteady compressible flows and applied know-how relevant for fluid machinery, aeronautical and propulsion applications.
At the end of the course the student will be able
- to understand the compressibility effects in steady subsonic, transonic and supersonic flows and in unsteady flows;
- to solve simple problems of preliminary design and performance verification of components for fluid machinery and airfoils with compressible flow;
- to solve problems of unsteady flow of a compressible fluid in 1D ducts;
- to analyse and discuss numerical and experimental results of compressible flow fields in nozzle, diffusers, airfoils and blade cascades.
Theoretical and applied lectures: presentation and discussion of the theoretical contents, numerical and experimental applications.
- Quasi-one-dimensional flow in variable-area ducts; nozzles and diffusers.
- Normal and oblique shock waves, expansion waves. Shock waves-boundary layer interaction.
- Unsteady wave motion: moving normal shock waves; method of characteristics for finite waves.
- Steady supersonic flow: theory and applications of the method of characteristics.
- Subsonic, transonic and supersonic flow on airfoils.
- Transonic and supersonic cascades for axial compressors and turbines.
