Frequency domain techniques for complex and nonlinear flows in turbomachinery

Conference Paper

In this paper, we review frequency domain techniques for computing unsteady flows in turbomachinery. The frequency domain approaches, which can be used to model both small-disturbance and nonlinear time periodic flows, are computationally very efficient, typically one to two orders of magnitude more efficient than time domain techniques. Furthermore, they can be used to analyze a wide variety of aeromechanic, performance, unsteady heat transfer, and flow stability problems in turbomachinery, including the important problem of unsteady flows in multistage machines. © 2003 by Kenneth C.
