Analytical Modeling Of A Novel Elastohydrodynamic Seal Design For Supercritical Co2 Power Cycles, Ikenna C. Ejiogu

Electronic Theses and Dissertations

Supercritical carbon dioxide (sCO₂) power cycles show great potential for higher plant efficiencies and power densities for a wide range of power generation applications such as fossil fuel power plants, nuclear power production, solar power, and geothermal power generation. sCO₂ leakage has been one of the main concerns in such applications, penalizing the cycle efficiencies. The effect of the seal leakage on the cycle efficiency could be as high as 0.65% for a utility sCO₂ power cycle. Therefore, there is a pressing need for effective sealing solutions to get the full benefit of sCO₂ power …
