The analysis of the effect of high-speed ammonia low-speed compressor stage on the processes of reverse expansion and suction in wet steam region
The paper presents a mathematical model of combined processes of reverse expansion and suction in the wet steam region, implemented in an ammonia low-speed long-stroke reciprocating compressor stage. The mathematical model is based on the equations of the first law of thermodynamics for a body of...

| Summary: | The paper presents a mathematical model of combined processes of reverse expansion and suction in
the wet steam region, implemented in an ammonia low-speed long-stroke reciprocating compressor
stage. The mathematical model is based on the equations of the first law of thermodynamics for a body
of variable mass, the equation of state of a real gas, the Clapeyron–Clausius and Newton–Richman
equations; various options for implementing the methodology for calculating the heat exchange process
in the working chamber of the stage are also considered. A computational and parametric analysis of
the effect of the piston speed on the performance losses of the compressor stage and on the degree
of dryness of ammonia at the end of the suction process is performed, taking into account the existing
uncertainty factors both in terms of the choice of methods for calculating heat exchange processes and
in terms of the choice of initial and initial conditions. |
