Paper Abstract

A numerical technique capable of simulating blade-scale compression system flow instabilities over time-scales spanning tens of rotor revolutions is presented. Simulations of stall inception, growth to fully developed rotating stall, and evidence for hysteresis, secondary instabilities, and other nonlinear phenomena are presented. Signal processing techniques for flow asymmetry characterization are discussed in the context of obtaining low-order representations of the flow disturbances with the ultimate goal of active stall suppression.
