Effects of Impeller Squealer Tip on Centrifugal Compressor Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes the main results sorted out from a design of experiment (DoE) based on a validated computational fluid dynamics (CFD). Several tip recessed geometries applied to an unshrouded impeller were considered ...
Innovative Cavity Modeling for Centrifugal Compressors Aeromechanical Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Centrifugal compressor aeromechanics is playing an increasingly important role in the energy transition scenario, especially when operating with low-molecular-weight gases, such as hydrogen. For these machines, maximum ...
Analysis 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 ...
Computational and Experimental Assessment of a MW-Scale Supercritical CO2 Compressor Operating in Multiple Near-Critical Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work illustrates the results of a wide experimental campaign in the frame of the EU-funded project sCO2-Flex, which focused on the investigation of a MW-scale sCO2 compressor operating in plant-representative conditions. ...
Implications of Phase Change on the Aerodynamics of Centrifugal Compressors for Supercritical Carbon Dioxide Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Closed Joule–Brayton cycles operating with carbon dioxide in supercritical conditions (sCO2) are nowadays collecting a significant scientific interest, due to their high potential efficiency, the compactness of their ...
