The Performance of a 6.5 Pressure Ratio Centrifugal Compressor having a Radially-Vaned Impeller

SUMMARY The aerodynamic design and experimental performance of a centrifugal compressor designed for a pressure ratio of 6.5 and a specific speed of 68 are described, The compressor consisted of a radially-vaned impeller and a transonic, vaned radial diffuser. At design speed a peak overall total-to-total isentropic efficiency of 0.746 was achieved at the maximum pressure ratio of 5.9, rising t...

Effect of Double Row Diffusers on Performance and Flow Field of a Centrifugal Compressor

The present paper reports measurements carried out in a centrifugal compressor equipped with double row of low solidity partial vane diffuser. Performance of the compressor is measured with three sets of double row diffusers with different radial spacing between the diffusers. From these measurements best configurations are identified and static pressures on the diffuser walls and probe measure...

Effect of impeller geometry on performance characteristics of centrifugal compressor

Centrifugal Compressors play an essential role in oil, gas and petrochemical industries. Their extensive usage is due to their smooth operation and high reliability compared to other other compressor types. One of the main characteristics of these turbomachines is their performance curve, which is an important criterion for selecting the appropriate compressor for a desired working condition. I...

the present study sought to investigate the role of dynamic assessment (da) in improvement of iranian efl writing performance at different language proficiency levels. to this end, after conducting the quick placement test, 60 iranian efl learners were assigned to two groups with different language proficiency levels. in both groups each participant wrote two compositions, one before and one af...

Performance Measurements of a Full-stage Centrifugal Process Gas Compressor Test Rig

The paper presents the first experimental performance data for a mid-stage centrifugal compressor test rig built at RWTH Aachen University. The results provide an analysis of the operational and loss behavior and will be published in an open test case for validating numerical methods. The test rig was built to investigate the operational and loss behavior of a complete return channel in detail ...
