RISAnalysis of the Flow-Field Distortions Induced by Pneumatic Pressure Probes in Test Bench Experiments on Centrifugal Compressors: Are We Testing Right?
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental testing at the test rig still plays a key role in the development of new centrifugal compressor designs for industrial applications. Although a wide set of different probes is used as per common practice, the ...
Experimental Analysis of the Pressure Field Inside a Vaneless Diffuser From Rotating Stall Inception to Surge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate estimation of rotating stall is one of the key points for highpressure centrifugal compressors, as it is often connected with the onset of detrimental subsynchronous vibrations which can prevent the machine ...
Analysis of the Rotordynamic Response of a Centrifugal Compressor Subject to Aerodynamic Loads Due to Rotating Stall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the current industrial research on centrifugal compressors, manufacturers are showing increasing interest in the extension of the minimum stable flow limit in order to improve the operability of each unit. The aerodynamic ...
A Systematic Approach to Estimate the Impact of the Aerodynamic Force Induced by Rotating Stall in a Vaneless Diffuser on the Rotordynamic Behavior of Centrifugal Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the main challenges of the present industrial research on centrifugal compressors is the need for extending the left margin of the operating range of the machines. As a result, interest is being paid to accurately ...
Design and Prototype Test Data for a 300 kW Active Magnetic Bearings-Supported Turbine Generator for Natural Gas Pressure Letdown
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A 300 kW integrated and fully sealed turboexpander-generator for natural gas pressure letdown (PLD) was developed by Baker Hughes, a GE company (BHGE), in conjunction with Calnetix Technologies. This paper describes the ...
A Three-Dimensional Time-Accurate Computational Fluid Dynamics Simulation of the Flow Field Inside a Vaneless Diffuser During Rotating Stall Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An accurate characterization of rotating stall in terms of inception modality, flow structures, and stabilizing force is one of the key goals for high-pressure centrifugal compressors. The unbalanced pressure field that ...
