Optimal Design of a Centrifugal Compressor Impeller Using

high compressor ratio and narrow installation space compared to axial-type compressors. In industrial fields, centrifugal compressors are also still widely used. Most turbochargers in vehicles adopt a centrifugal-type compressor. The efficiency of a centrifugal

Failure Investigation of a Gas Compressor Impeller

In the Lacq plant located in the south-west of France, good service has been obtained with compressor fit with 16%Cr 4%Ni martensitic stainless steel impellers for more than 20 years. Hence, it was a surprise when a failure occurred in one of the compressors in 2004.

Suppression of secondary flows in a transonic centrifugal

N2 - Secondary flows in transonic centrifugal compressor impellers affect their aerodynamic performance. In open-type impellers, low energy fluids can accumulate on the suction surfaces near the trailing edge tip side since the secondary flows and tip leakage flows interfere each other and complex flow phenomena can be generated around the impellers.

Back to Basics Selecting a Centrifugal Compressor

Impellers — the heart of the centrifugal compressor The most critical components in any centrifugal com-pressor, regardless of style, are the impellers. If the impel-lers do not provide a high efficiency and good overall flow range, it is impossible for the compressor
