The main objective of this course is to familiarize the students with the physical phenomena, mechanisms and basic computations behind turbomachinery flows.Starting with aerodynamics and thermodynamics applied to turbomachinery, we will detail the main tools used in the design of turbomachines. More specifically, we will tackle the design of an axial compressor given a specific efficiency objective.Practical work on a dedicated axial low-speed compressor test bench will be helpful to apprehend theoretical notions seen in class in a concrete case. Tutorial sessions will be devoted to the design of an axial compressor given specific objectives.
