The practice of designing centrifugal compressors in which impellers are the main components shows that there reserves for their further improvement. One consists improving flow conditions compressed medium compressor setting and, above all, impeller. A method geometric modeling settings was proposed involves construction meridional boundaries and blade profile on an involute cylindrical surfac...

The performance of a multistage centrifugal compressor is highly influenced by the ambient conditions, especially during summer seasons; their capacity shrinks and thus power requirement for compression will increase. prime cause these constraints interstage cooling limitations. This study simulates various suction conditions on Aspen HYSYS® suggests its debottlenecking making temperatures comp...

An air compressor is the core component of supply system a hydrogen fuel cell, which demands high efficiency and reliable stability in wide operation region. In this work, centrifugal for cell first designed then measured experimentally. Furthermore, test rig assessing aerodynamic performance established, includes pipeline, gas flowmeter, flow regulating valve, pressure transmitter, compressor,...

A high-speed centrifugal air compressor structure supported by aerodynamic pressure bearings and driven a permanent magnet synchronous motor was proposed. The integration of lubrication is realized, which meets the fuel cell system's requirements for oil-free efficient. Based on analysis principle bearing motor, parameters each component were designed, prototype developed. When working at 10×10...
