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...
متن کاملThe 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...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Optimum Operating Pressure Ratio for Scroll Compressor
A scroll compressor has a bu~lt-in pressure ra~~o related to geometry of scroll wraps and efflciency of the compressor depends on the relation between the ratio and an operat~ng pressure rat~o. Th~s paper analyses theoretl.cal performance of the compressor by tak1ng account of flow resistances at opem.ngs of scroll wraps and leakage flows through wrap clearances. The flow resl.stance at the d1s...
متن کاملPositive feedback stabilization of centrifugal compressor surge
Stable operation of axial and centrifugal compressors is limited towards low mass 1ows due to the occurrence of surge. The stable operating region can be enlarged by active control. In this study, we use a control valve which is fully closed in the desired operating point and only opens to stabilize the system around this point. As a result, only nonnegative control values are allowed, which co...
