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 کاملOptimal Design of a Centrifugal Compressor Impeller Using Evolutionary Algorithms
An optimization study was conducted on a centrifugal compressor. Eight design variables were chosen from the control points for the Bezier curves which widely influenced the geometric variation; four design variables were selected to optimize the flow passage between the hub and the shroud, and other four design variables were used to improve the performance of the impeller blade. As an optimiz...
متن کاملAn Aerodynamic Investigation of a Centrifugal Compressor for HCFC123
The experimental investigation of a centrifugal compresso r is carried out to improve HCFC123 compression performance. A CFCll c ompressor applying HCFC123 shows a lowered adiabatic head rise, efficie ncy, and volume flow. Another CFC!l compressor with HCFC123 and a modifie d impeller shows a result comparable to the CFCll compression case. A tan dem impeller is designed to cover the volume flo...
متن کاملEffects of Impeller Gap on Rotor Vibration in a High Speed Centrifugal Compressor: A Numerical and Experimental Analysis (TECHNICAL NOTE)
Centrifugal compressors produce high pressure ratio and rotate at speeds. So, a tiny unbalance can produce severe vibration. In this paper, effects of impeller gap on rotor vibration in a high speed centrifugal compressor is investigated. For this purpose, a numerical and experimental analysis are carried out. The moving reference frame method in FLUENT software is used for modeling of geometri...
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...
