Assessing Liquid Droplet Erosion Potential in Centrifugal Compressor Impellers
This paper presents a method for estimating the potential for liquid droplet erosion in compression system components, such as the impeller of centrifugal compressors. The erosion model selected is used to calculate a threshold velocity that represents the limit for the onset of erosion damage. The parameters used in the model include the liquid phase density and viscosity, impeller geometry, s...
متن کاملDynamic centrifugal compressor model for system simulation
A dynamic model of a centrifugal compressor capable of system simulation in the virtual test bed (VTB) computational environment is presented. The model is based on first principles, i.e. the dynamic performance including the losses is determined from the compressor geometry and not from the experimentally determined characteristic performance curves. In this study, the compressor losses, such ...
متن کاملManufacturing and Testing Experience with Direct Metal Laser Sintering for Closed Centrifugal Compressor Impellers
Direct Metal Laser Sintering (DMLS) is an additive manufacturing process that utilizes a high-powered laser to build up a metal part by selectively melting thin layers of metal powder. This process is attractive for the manufacturing of parts with complex geometry such as closed centrifugal compressor impellers. DMLS allows closed impellers to be made in a single piece and eliminates the shroud...
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 کاملEffect 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...
