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.

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it), the Polytechnic School's disability liaison.

 

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.

- Transonic and supersonic cascades for axial compressors and turbines.

EXAMS

EXAM DESCRIPTION

Oral examination.

Students with SLD, disability or other regularly certified special educational needs are advised to contact the instructor at the beginning of the course to agree on teaching and examination methods that, in compliance with the course objectives, take into account the individual learning requirements.

ASSESSMENT METHODS

Discussion of at least two topics treated during the lectures.

The examination will be aimed at evaluating the knowledge level, the ability of solve simple problems, the critical analysis skills, the clarity of exposition.
