RISValve fault detection for single-stage reciprocating compressors
In the present study, a zero-dimensional numerical method is developed based upon the crank angle to investigate reciprocating natural gas compressor with valve faults. This model aims to take piston movement, valve dynamic, ...
Thermodynamic analysis of a CNG refueling station considering the reciprocating compressor
CNG refueling station, including on-board NGV cylinder, reservoir tanks, connecting pipes and especially reciprocating compressor. Unlike most previous researches, pressure variation of the reservoir tanks during the filling process have been...
Thermodynamic analysis of natural gas reciprocating compressors based on real and ideal gas models
The accurate modelling and investigating effects of various parameters of the reciprocating compressors are important subjects. In this work, based on first law of thermodynamics, conversation of mass and real and ideal gas assumptions, a...
Numerical simulation of pressure pulsation effects of a snubber in a CNG station for increasing measurement accuracy
Local natural gas companies in Iran employ turbine flow meters to measure natural gas which
is delivered to Compressed Natural Gas (CNG) stations at low pressure. The stations, then, utilize
reciprocating compressors to increase...
Exergy analysis and entropy generation of a reciprocating compressor applied in CNG stations carried out on the basis models of ideal and real gas
In this work, a numerical analysis for observing the proficiency of reciprocating compressors used in CNG (Compressed Natural Gas) stations is studied thermodynamically for ideal model and real one. AGA8 state equation is intended for modeling real...
