RISInvestigation of Unsteady Rotor–Stator Interaction and Deterministic Correlation Analysis in a Transonic Compressor Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unsteady blade row interaction (UBRI) has a large impact on performance in high-speed axial compressors. Thus, the influence of UBRI should be accurately predicted in compressor routine design. In this study, the unsteady ...
Unsteady Flow Structure of Corner Separation in a Highly Loaded Compressor Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Corner separation is an inherently unsteady flow feature in an axial compressor cascade, and it significantly affects the aerodynamic performance of compressors. The flow field of a highly loaded compressor cascade at the ...
Unsteady Flow Mechanism of Corner Separation Control Using Blade End Slots in a Highly Loaded Compressor Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blade end slots have been proven to be an effective method to suppress corner separation, thereby improving the aerodynamic performance of the compressor. The unsteady effects of blade end slots affiliated with a highly ...
An Exponential Decay Model for the Deterministic Correlations in Axial Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The unsteady blade row interaction (UBRI) is inherent and usually has a large effect on performance in multistage axial compressors. The effect could be considered by using the average-passage equation system (APES) in ...
Modification of Shear Stress Transport Turbulence Model Using Helicity for Predicting Corner Separation Flow in a Linear Compressor Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional corner separation significantly affects compressor performance, but turbulence models struggle to predict it accurately. This paper assesses the capability of the original shear stress transport (SST) ...
