Abstract

Since most of the aerodynamic losses in turbomachinery are directly related to the various viscous flow phenomena, a reliable computer program for three-dimensional compressible viscous flows in cascades and ducts is an effective design tool for improving the performance of modern turbines and compressors. The recent remarkable advances in computer capabilities and solution algorithms enable the calculation of fully three-dimensional viscous flows and several such computer programs have been developed in recent years. Moore et al. (1979) and Hah (1983) proposed the computer programs for three-dimensional viscous compressible flows in ducts and cascades. Although both of them are available for compressible flow calculations, they are hardly applicable to transonic flow analysis.
