Aims :

The course deepens the thermo and fluidynamic phenomena and gives the basic design criteria for turbo-machineries as turbines and compressors.

Topics :

Fludynamic equations for the flow of a non-reacting, compressible and uncompressible, steady and unsteady, viscous and unviscid perfect fluid. Reference systems. Normal shocks. Quasi-one dimensional flow. Nozzles and diffusors. Viscous and adiabatic one dimensional flow (Fanno flow). Heat exchanging inviscid flow (Rayleigh flow). Axial compressors and turbines. The fluidynamic analysis of the stage. The reaction grade. Blade profiles and cascades. Fluidynamic losses and deviation angles. Experimental and numerical methods for the performance previsions. Efficiency. The performance curves. Off design performance for a single and twin-shaft gas turbine and a turbojet.
