Performance modeling of centrifugal and mixed-flow compressors and pumps has developed substantially over the past decades. The first half of the 1900s provided important insights as to the basic structure of the fluid dynamic process; the period from 1960 to 2005 provided 45 years of continuous analytical modeling development. Throughout the past century, the radial turbomachinery field awaited the development of a comprehensive loss, diffusion, and deviation modeling system similar to those that evolved for axial turbomachinery. Recently, a concrete foundation for an appropriate modeling system has developed. In this presentation, the basic models are reviewed and, in turn, the available database (more than 250 cases) is surveyed. A fully computerized, data synthesis process, employing optimization search techniques, is presented by which new analytical models can be thoroughly matched to available data.
