Introduction to unsteady flows in turbomachines
Abstract
The basic fluid mechanic aspects of unsteady flow in turbomachines are discussed. The unsteadiness is seen to arise from several different sources, and to have an impact on the overall behavior of the machine. The topics covered are: (1) basic consideration of unsteady flow and inherent unsteadiness of turbomachinery, (2) sources of unsteady flows and relevant parameters, (3) illustrative examples of unsteady flow, (4) unsteady effects with uniform inlet flow, and unsteady effects with nonuniform flow (inlet distortion).
