The flowfield in turbomachinery components has been considered to be one of the most difficult problems in the past. With the advent of computational fluid dynamics (CFD) methods, many difficult turbomachinery flow problems can now be solved with a good degree of accuracy. The objective of this paper is to describe the applications of computational techniques in various turbomachinery related analysis and design. Three-dimensional Navier-Stokes solvers and interactive grid generator were used as the tools in these studies. The examples shown include axial and centrifugal flow impellers at steady and/or unsteady operating conditions. The problems discussed have different degrees of complexity ranging from a simple axial flow fan calculation to more complicated unsteady rotor-stator interactions. The key points of each problem and the solution procedures are described. The solutions and their physics are also discussed.
