Turbomachinery Aerodynamics

This course is about turbomachinery aerodynamics, which will basically be looking at the aerodynamics of the flows associated with turbo machines, the various types of turbo machines and the theory behind working of these different types of turbo machines. This course covers various aspects of the aerodynamics associated with the different types of turbomachines like axial compressors, axial turbines, and centrifugal compressors, and radial turbines.
