OVERVIEW

The course deepens the physical phenomena due to the flow compressibility, which occur in steady subsonic, transonic and supersonic flows , and the wave motion in unsteady flows.

AIMS AND CONTENT

LEARNING OUTCOMES

The course provides basic knowledge on steady and unsteady compressible flows and applied know-how relevant for fluid machinery, aeronautical and propulsion applications.

AIMS AND LEARNING OUTCOMES

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. 

TEACHING METHODS

Theoretical and applied lectures: presentation and discussion of the theoretical contents, numerical and experimental applications.

SYLLABUS/CONTENT

- 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.
