RISExperimental Study on the Effect of Diffuser Vane Setting Angle on Centrifugal Compressor Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of the diffuser vane setting angle on the performance of a centrifugal compressor was experimentally investigated. Seven different vaned diffusers were tested with the same impeller. In order to evaluate the ...
A Study on Matching Between Centrifugal Compressor Impeller and Low Solidity Diffuser and Its Extension to Vaneless Diffuser
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A centrifugal compressor requires a wide operating range as well as a high efficiency. At high pressure ratios, the impeller discharge velocity becomes transonic and effective pressure recovery in a vaned or vaneless ...
A Method for Preliminary Design of Variable Geometry Vaned Diffuser for Centrifugal Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Centrifugal compressors require a wide operating range as well as high efficiency. Typical active control forms to enhance the operating range are suction throttling with a valve in a suction line, discharge throttling ...
Experimental Investigation of High Pressure Ratio Centrifugal Compressor With Axisymmetric and Nonaxisymmetric Recirculation Device
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Centrifugal compressors used for turbochargers are required to have a wide operating range. A recirculation device, which consists of a bleed slot, an upstream slot, and an annular cavity connecting both slots, is often ...
Stability Improvement of High Pressure Ratio Turbocharger Centrifugal Compressor by Asymmetrical Flow Control—Part II: Nonaxisymmetrical Self Recirculation Casing Treatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This is part II of a twopart paper involving the development of an asymmetrical flow control method to widen the operating range of a turbocharger centrifugal compressor with highpressure ratio. A nonaxisymmetrical ...
A Transonic Mixed Flow Compressor for an Extreme Duty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the design of a transonic mixed flow compressor stage for an extreme duty, with an extremely high flow coefficient (د†) of 0.25 and a high isentropic pressure rise coefficient (دˆ) of 0.56. The impeller ...
Effects of Blade Deformation on the Performance of a High Flow Coefficient Mixed Flow Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of blade deformation under running conditions on the performance of a highly loaded transonic mixed flow impeller were investigated. Two impellers were manufactured, one using the “running†blade profiles ...
Enhancement of Centrifugal Compressor Operating Range by Control of Inlet Recirculation With Inlet Fins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The operating points of a turbocharger compressor tend to approach or cross its surge line while an engine is accelerating, particularly under lowengine speed conditions, hence the need for an acceptable surge margin under ...
Stability Improvement of a Turbocharger Centrifugal Compressor by a Nonaxisymmetric Vaned Diffuser
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nonuniformity of the flow field induced by a nonaxisymmetric volute significantly degrades the stability of a turbocharger centrifugal compressor. In this paper, a nonaxisymmetric vaned diffuser is investigated as a ...
Stability Improvement of High Pressure Ratio Turbocharger Centrifugal Compressor by Asymmetric Flow Control—Part I: Non Axisymmetrical Flow in Centrifugal Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This is Part I of a twopart paper documenting the development of a novel asymmetric flow control method to improve the stability of a highpressureratio turbocharger centrifugal compressor. Part I focuses on the nonaxisymmetrical ...
