Bibliography

Bibliography This bibliography on carbon dioxide snow cleaning has been complied with the intent to list all publications. The list is from mostly manufacturers, or their agents, and these papers generally discuss methods and applications. Papers and reports from users can be included too. We want them!!! Please note, only papers related to snow cleaning are included. We need inp...

Cleaning Mechanisms.

Cleaning Mechanisms Thermodynamically, we shown that the passage of either liquid or gaseous CO2 through an orifice can lead to the formation of dry ice or snow. With proper nozzle geometry the snow stream can obtain high velocities and effectively remove both particulate and organic contamination. The removal of organic and particulate residues from surfaces during CO2 snow clea...

Thermodynamics of CO2 Snow Formation The carbon dioxide phase diagram has 3 phases -- gaseous, liquid, and solid. The triple point (pressure 5.1 atm., temperature - 56.7C) is defined as the temperature and pressure where three phases (gas, liquid and solid) can exist simultaneously in thermodynamic equilibrium. Above the critical point (pressure 72.8 atm., temperature 31.1C ) the...
