Rotating Stall Induced Non-Synchronous Blade Vibration Analysis for an Unshrouded Industrial Centrifugal Compressor [PDF]
Sensors, 2019 Rotating stall limits the operating range and stability of the centrifugal compressor and has a significant impact on the lifetime of the impeller blade. This paper investigates the relationship between stall pressure wave and its induced non-synchronous

Detection of vaneless diffuser rotating stall by means of dynamic pressure sensors and acoustic measurements [PDF]
E3S Web of Conferences, 2021 An accurate estimation of rotating stall is one of the key technologies for high-pressure centrifugal compressors. Several techniques have been proposed to detect the stall onset; inter alia, few dynamic pressure probes have been shown to not only ...

Inboard Stall Delay due to Rotation [PDF]
Journal of Aircraft, 2011 In the design process of improved rotor blades the need for accurate aerodynamic predictions is very important. During the last years a large effort has gone into developing CFD tools for prediction of wind turbine flows (Duque et al., 2003; Fletcher et al., 2009; Sorensen et al.,2002).

Influence of axial spacing on stall development of FBCDZ-10-No20 mode contra-rotating fan
Meitan kexue jishu, 2023 The rotating fan is prone to instability such as stall and even surge when operating at low flow rates. In order to study the influence of axial spacings on the stall inception and its development and propagation process of a contra-rotating fan , a ...

Estimations of Compressor Stall and Surge Using Passage Stall Behaviors
Machines, 2022 The predictions of the onset of rotating stall and surge are very important in the preliminary design stage of a compressor. Rotating stall and surge are complex instabilities that cause efficiency loss and reduced pressure rise, and, therefore ...
