Experimental and numerical simulation of a novel on-line leak sealing technology based on magnetorheological adhesive
Emergency leakage sealing plays a crucial role in accident control. This study proposes a novel emergency sealing method for pipeline leaks based on magnetorheological adhesive. A full-scale leakage simulation experiment was conducted on the DN350 pipeline, and the online sealing pressure could reach 1.5 MPa. After repair, the pressure-bearing capacity could be further improved. In addition, the quantitative relationship between leakage conditions and plugging parameters was studied by finite element simulation, the magnetic force can be increased by 2.0–6.3 times by adding the magnetorheological adhesive. The sealing mechanism was explained from the perspective of magnetic field, flow field, and stress changes.
期刊介绍：
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
