Compressor Surge in Gas Turbines and Blast Furnace Compressor Installations
Journal of Engineering for Power, 1965The character of different surge cycles is described, and the corresponding influence on the dynamic loading of the blades of axial flow compressors is discussed. It is shown that essentially fatigue is governed by the rapidity of loading or unloading of the blading.

Gas Dynamic Designs of Centrifugal Compressors for Gas Industry
ASME 2015 Gas Turbine India Conference, 2015Centrifugal compressors for gas industry consume huge amount of energy. As a rule, they are single-shaft, with two or more stages and with comparatively low pressure ratio. Compressors operate at low Mach numbers and high Reynolds numbers. Two design parameters influence mostly stage performances.

Prediction of gas pulsation of an industrial compressor
Journal of Central South University, 2013The measurement and prediction of gas pulsations are performed along the discharge pipeline of a reciprocating compressor for a refrigerator. A regression based experimental model of the one-dimensional acoustic field is developed. First, the conventional method for gas pulsation measurement and prediction, which separates the incident and reflected ...

Performance of Gas Turbine Compressor Cleaners
Journal of Engineering for Gas Turbines and Power, 1992Deposits are regularly removed from compressor blades and vanes of installed jet engines and gas turbines by compressor washing. A compressor cleaner is sprayed into the compressor while operating at reduced or normal rpm. Recently developed compressor cleaners are claimed to be ecologically sound.

Failure analysis of a gas turbine compressor
Engineering Failure Analysis, 2011Abstract During the shut down period, a 32 MW gas turbine experienced a severe failure accompanied by a loud noise near its second natural frequency at 4200 rpm. After opening the turbine casing, it was revealed that the disks of stages 16 and 17 of the compressor had been fractured and all of the stationary and rotary blades of stages 14–18 of the ...

Wet Gas Compressor Operation and Performance
Volume 6A: Energy, 2018The continuous demand for oil and gas forces the petroleum industry to develop new and cost-effective technologies to increase recovery from new fields and enhance extraction from existing fields. Subsea wet gas compression stands out as a promising solution for increasing production capacity, utilizing remote regions and reducing costs.

An oil-free gas-tight compressor [PDF]
Journal of Scientific Instruments, 1951 A new non-contaminating piston-type compressor is described. A highly flexible rubber diaphragm behind the piston acts as a gas-tight gland and also separates the lubricated parts which drive and guide the piston from the space swept out by the piston itself, in which there is no fluid lubricant.

Reciprocating Gas Compressors and Motors
1979These are process, as distinct from cyclic, devices in which the fluid undergoes a state change, not a cyclic process. Only in the finite clearance case does a small proportion of air continually undergo cyclic changes, without affecting the state of the processed fluid in any way.

Compressor discharge gas sound attenuation
The Journal of the Acoustical Society of America, 1992A hermetic motor-compresosr having separate discharge cavities in the compressor body for each pumping cylinder, a common discharge gas plenum for the entire compressor, and an impedance tube between each cavity and said plenum, thereby signficantly improving the sound attentuation of discharge gas pulses.
