The experimental results indicated that the application of the AEFTD could effectively reduce fouling resistance and decelerate the growth rate of CaCO3 fouling. The opposite trend between fouling resistance and the outlet temperature of an experimental fluid indicated that the application of the AEFTD could enhance heat transfer. Meanwhile, the crystal morphologies of the fouling samples were analyzed by means of scanning electron microscopy (SEM). The axial-electromagnetic field favored the formation of vaterite as opposed to calcite. Non-adhesive vaterite did not easily aggregate into clusters and was suspended in bulk to form muddy fouling that could be carried away by turbulent flow. Furthermore, the anti-fouling mechanism of the axial-electromagnetic field is discussed in detail. The anti-fouling effect of the AEFTD on CaCO3 fouling exhibited extreme characteristics in this study. Therefore, the effectiveness of the AEFTD is contingent upon the selection of the electromagnetic parameters.<\/jats:p>","DOI":"10.3390\/e25070962","type":"journal-article","created":{"date-parts":[[2023,6,22]],"date-time":"2023-06-22T02:29:18Z","timestamp":1687400958000},"page":"962","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Influence of an Axial-Electromagnetic Field Treatment Device with a Solenoid Structure on Crystallization Fouling on the Tube Side of a Shell-and-Tube Heat Exchanger"],"prefix":"10.3390","volume":"25","author":[{"given":"Yaxuan","family":"Peng","sequence":"first","affiliation":[{"name":"School of Civil Engineering and Architecture, Northeast Electric Power University, Jilin 132012, China"}]},{"given":"Xuefei","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, Northeast Electric Power University, Jilin 132012, China"}]},{"given":"Yandong","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Automation Engineering, Northeast Electric Power University, Jilin 132012, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113283","DOI":"10.1016\/j.rser.2023.113283","article-title":"Plate heat exchangers fouling mitigation effects in heating of water solutions: A review","volume":"179","author":"Kapustenko","year":"2023","journal-title":"Renew.
