The ensemble of lectures belonging to this discipline provides to the students the main tools requested for the design and analysis of the flow field of turbomachinery of different architectures, sizes and applications.
Classic theories providing the basic laws of the fluid motion, compressibility effects responsible for the formation of shock and expansion waves into supersonic applications, viscous effects providing the boundary layer theory and related loss generation mechanisms, are introduced and discussed.
These notions will be adopted for a better understanding of the effects induced by the variation of geometrical and flow parameters on the operation of turbine and compressor stages, thus providing further insight to be adopted in 1-D , 2-D and 3-D design steps including state of the art constrains. Particularly, the role played by the loading distribution on the loss generation will be directly inspected in order to optimize viscous effects generating over the blade surfaces, as well as by the shock generating at the leading edge and into supersonic stages.
Lectures devoted to the study and design of turbomachinery will provide the opportunity to completely define the surfaces of the different elements of the machine, thus allowing the simulations of the flow field with different degree of fidelity (RANS, URANS and LES);
Experimental techniques for fluid dynamic applications, and related post-processing algorithms, complement the notions provided in this discipline, thus further contributing to a better understanding of the tridimensional and unsteady flow field characterizing the internal aerodynamic of real compressors and turbines.
