During large-scale hydraulic fracturing in shale gas horizontal wells, a cement sheath easily loses its integrity due to the fluctuation and continuous change of wellbore temperature and pressure and the cyclic loading and unloading, which will threaten wellbore integrity. In order to figure out the...

In this study, a numerical simulation of magnetic nanoparticles in an insulating fluid was developed to model particle tracing for AC breakdown mechanisms happened to a sphere鈥搒phere electrode configuration and to propose a possible mechanism regarding the change in the breakdown strength due to...
The stability of proposed scheme is rigourously established, and nearly optimal order error estimate is also derived. Numerical experiments are conducted to support the predicted convergence rates and also exhibit expected super-convergence phenomena....
