The Estimation of Expediency of the Cylinder Internal Finning in the Single-stage Compressor with a Temporary-rotary Operating Mode

The paper presents the calculation methodology of the numerical experiment of the gas flowing in the single-stage compressor with a temporary-rotary operating mode with the internal finning of the cylinder. The numerical results of the research obtained on the basis of the programme KOMDET-M are represented in the paper. The expediency and inexpediency of the internal finning of cylinders in the stages of the low-consumption compressors with small-size cylinders and minimum gas density under suction at the moderate shaft speed and intensive (water) cooling is proved.
