An Evaluation Approach for the Stall Margin Enhancement With Stall Precursor Suppressed Casing Treatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is known that a kind of stall precursorsuppressed (SPS) casing treatment can be used to enhance compressor stall margin (SM) without recognizable efficiency loss. The further requirement in this regard is to develop an ...
Basic Studies of Flow Instability Inception in Axial Compressors Using Eigenvalue Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper applies a theoretical model developed recently to calculate the flowinstability inception of an axial transonic single stage compressor. After several calculation methods are compared, the singular value ...
Stall Inception Analysis of Transonic Compressors With Chordwise and Axial Sweep
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper concentrates on the stall inception analysis of transonic compressors with chordwise and axial sweep. A new prediction approach of stall inception is developed based on global stability analysis and immersed ...
Analysis Method of Compressor Stability Based on Eigenvalue Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to analyze the flow stability of compressors rapidly in the design stage, a fast analysis method is developed in this paper. This method takes the base flow on each streamline at different spanwise locations as ...
Calculation of Flow Instability Inception in High Speed Axial Compressors Based on an Eigenvalue Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper applies a theoretical model developed recently to calculate the flow instability inception point in axial high speed compressors system with tip clearance. After the mean flow field is computed by 3D steady ...
Further Investigation on Transonic Compressor Stall Margin Enhancement With Stall Precursor Suppressed Casing Treatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A kind of casing treatment, named as stall precursorsuppressed (SPS), has been developed recently, which was proved to be able to effectively improve stall margin (SM) without significant efficiency loss in lowspeed axial ...
Further Investigation on Acoustic Stall-Warning Approach in Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A further investigation of an acoustic theory-based stall-warning approach is presented in this paper, which contains the basis of this approach and an application on a low-speed compressor (LSC) with a stabilization system. ...
Sensitivity Analysis for Flow Stability of Axial Compressor Based on Meridional Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A sensitivity analysis method for flow stability of axial compressors based on meridional flow is proposed and employed to reveal the sensitive region of stability in the present article. The meridional stability model ...
Stall Inception Analysis on Axial Compressors With Different Rotor Loading Distributions Under Radial Inlet Distortions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stability studies were conducted on a single-stage, low-speed compressor with different rotor loading-distribution designs under a uniform inlet, 10% intensity, and 20% intensity total tip pressure distortion inlet conditions ...
Model Verification and Experimental Study of the Turbomachinery Wake Flow Field Reconstruction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A clear understanding of the turbomachinery wake flow field is one of the key problems in developing turbomachinery aerodynamics. The theoretical model of helical vortices is established in cylindrical coordinates (r,θ,z), ...
