An extensive network of pipeline systems is used to transport and distribute national energy resources that heavily influence a nation's economy. Therefore, the structural integrity these must be monitored maintained. However, damage detection remains challenge in engineering. To this end, study developed modified electromechanical impedance (EMI) technique for crack involves fusing information from multiple sensors. We derived new damage-sensitive feature factor based on EMI model considers...

Low-salinity water (LSW) flooding has become a quite simple, effective, and economically feasible enhanced oil recovery (EOR) technology under the background of low price. The B425 block with permeability in Shengli oilfield, China, achieved an excellent LSW performance, but main EOR mechanisms are still not clear. Therefore, order to investigate block, set core-flooding experiments were conducted. contact angle on core slice zeta potential rock particle also measured. Then discussed....
Electromagnetic acoustic transducer (EMAT) is a kind of non-contact ultrasonic transducer, and during its operation, no liquid coupling required. Despite this advantage, EMAT has low transduction efficiency performance depends on the tested object, thus further research complex multiphysics mechanism involving both electromagnetic elastodynamic phenomena paramount. In paper, an approach to solve directly underlying integro-differential equations involved in eddy current model was proposed,...
