| Summary: | Leakage of the working substance in the compressor's flow gaps accounts for a large share of its
volumetric losses. The optimality of calculated and approximated characteristics depends on the accuracy
of quantitative component determination. Accordingly, an adequate and qualitative mathematical model
should include the factor of non-stationarity of the leakage process, taking into account the mobility
of scroll elements. At the same time, the real properties of the working medium, characterized by the
compressibility coefficient, play an important role in the nature of leakage. Thus, in this article the task of
creating a mathematical model adequate to the actual process of compression and allowing to estimate
the degree of influence of the slit walls mobility on the leakage through them is set. The result of
numerical calculations has a smaller error in relation to experimental data, and it also showed a significant
influence on the leakage rate of both the pressure difference at the edges of the slot and the viscosity
properties of the vapour-oil mixture, a significant percentage of which is oil. |
