Fan Stability With Leading Edge Damage: Blind Prediction and Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper considers the impact of a damaged leading edge (LE) on the stall margin and stall inception mechanisms of a transonic, low-pressure ratio fan. The damage takes the form of a squared-off leading edge over the ...
Mid-Span Stall Inception in Low-Pressure-Ratio Transonic Fans
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, steady and unsteady computational fluid dynamics (CFD) have been used to investigate stall inception for a modern low-pressure-ratio transonic fan. The computational results are validated against measurement ...
Stall Inception in Low-Pressure Ratio Fans
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A combined experimental and computational test program, with two low-pressure ratio aero-engine fans, has been used to identify the flow mechanisms at stall inception and the subsequent stall cell growth. The two fans have ...
