Wellbore leakage risk management in CO2 geological utilization and storage: A review

open access: yesEnergy Reviews, 2023
CO2 geological utilization and storage (CGUS) is an important technology to achieve a deep cut of global CO2 emissions. CO2 leakage from the subsurface may impair the performance of CGUS projects, and the CO2 leakage through wellbores is the most common ...

Sealing - Treatment Repair Technology of Cast Magnesium Alloy Shell Parts [PDF]

open access: yesCailiao Baohu, 2021
Due to the various degrees of internal defects (e.g. shrinkage, corroded points) in cast magnesium alloy shell, the fluid is easy to leakage. This kind of leakage has the characteristics of small leakage, many leakage points and difficulties to accurate ...

Frequency Dependent Model of Leakage Inductance for Magnetic Components [PDF]

open access: yes, 2012
Theoretical methods for the calculation of winding losses with respect to frequency have been well documented, but the variation in leakage inductance of magnetic components due to frequency has been less well addressed. In this paper Dowell’s well-known

A Computationally Efficient Hybrid Leakage Model for Modeling Leakage in Positive Displacement Compressors [PDF]

open access: yes, 2012
An empirical frictional correction factor to the isentropic nozzle model has been developed for application to leakage modeling in scroll, rotary and other similar compressors. This correction factor is derived by calculating the leakage mass flow with a

Bacterial leakage assessment in root canals sealed with AH Plus sealer modified with silver nanoparticles

open access: yesBMC Oral Health, 2021
Background Successful endodontic therapy requires prevention of bacterial leakage between the root canal filing and root-canal walls. Sealing quality of a root canal filling depends strongly on the sealing ability of the sealer used.
