The result is a performance map, representing the maximum possible performance for a given set of coefficient values. Profile designs are optimized for a range of target flow coefficients and work coefficients.

This paper details the development of new Smith charts for axial compressor designs, by making extensive use of optimization techniques. Most attempts to develop Smith-like charts for compressor design guidance are based on fairly simplified models that carry significant unknowns, particularly at high loading. Despite the widespread use of the Smith chart method, these approaches have a very limited substantiation and no clear pedigree. Similar, but less well-documented methods, have been developed for axial compressor design. The method was based on a significant set of test data for various turbine designs, corrected for complicating factors, such as various clearance gaps and so on. This approach was documented in detail by Smith and quickly became a preferred approach for initial design of axial turbines stages. The best-known guidelines for axial designs are the so-called “Smith Charts”. Guidance for these target velocities comes from a variety of sources, which include some physics-based rules but, more often than not, have a significant empirical basis. Preliminary design of a turbomachinery stage usually begins with target flow states, represented by a velocity triangle.
