Università Roma Tre

PART 1: ELEMENTS OF GAS_DYNAMICS
Introductory concepts; isoentropic compressible flows and normal shock waves; design of gas-dynamic systems. Fanno and Rayleigh flows. Oblique shocks and odograph plane. Prandtlt-Meyer expansion. Compressible potential flows, linear theory and supersonic thin qirfoil. Characteristic method (in 2D and steady).
PART 2: AIRCRAFT PROPULSIVE SYSTEMS
Introductory concepts and classification. Performance parameters. Definition of thrust and power. Definition of efficiencies. Turbo-gas cycle (real and ideal). Simple turbojet; turbofan; ramjet; turboprop. Propellers and blade element theory. Nozzles and diffusera (sub- and super-sonic).
PART 3: ELEMENTS OF HYDRODYNAMIC STABILITY
Introduction to stability analysis in fluid mechanics; vortex sheet; temporal and spatial stability; governing equations, Rayleigh and Orr-Sommerfeld equations; stability of shear and wall-bounded flows; Rayleigh's inflection point theorem; numerical methods for solution of stability problems; modal and non-modal stability; state-space representation of dynamical systems.
Several practical exercises are carried out during the course.
