... at the component level is the lack of suitable shaft seals in sCO 2 operating conditions. So far, all conventional seals are incapable of handling sCO 2 pressures and temperatures in one way or another. Hence, we propose an elastohydrodynamic (EHD) high-pressure, high-temperature, and scalable shaft seal for sCO...

... 31 03 2008 In the present paper dynamic friction processes in seals are investigated. The undesired stick-slip effect of these components under real technical conditions is analyzed. Starting with the basics of stick-slip vibrations the development of an advanced seal design...
