Analysis of the crystal formation process of carbon dioxide in a flowing part of the centripetal turbine expander
Annotation
The mathematical model developed by the author of freezing carbon dioxide in the low-temperature expansion turbines allows to analyze the main stages of the process of crystal formation. Matches rate of crystal nucleation and crystal growing specific weight per unit volume of the expanding gas stream. Track changes the image size and the growing crystals, as well as the average size of the resulting crystals. It indicates the relationship size growth and specific mass of crystals. The comparison of changes in the specific gravity of the crystals and the size of the bulk crystals with different initial parameters expandable gas mixture: pressure and vapor concentration of carbon dioxide. An important result of the analysis was the conclusion that the main crystal growth occurs behind the Wilson area.
