The detailed aerodynamic design of centrifugal compressor stage components relies heavily on the use of internal flow analysis methods, such as the quasi-three-dimensional flow analysis method presented in Chapter 12 and the blade-to-blade flow analyses of Chapters 13 and 14. These so-called Euler methods neglect the effects of viscosity in the interest of obtaining the computational speed and fast response a designer needs for the iterative process of establishing the annulus wall contours and blade geometry. These inviscid flow analyses provide valuable guidance to the designer in the form of blade loading distributions and velocity or pressure distributions along the...
