20.500.12556/RUL-128872 A review of crystallization fouling in heat exchangers A vast majority of heat exchangers suffer from unwanted deposition of material on the surface, which severely inhibits their performance and thus marks one of the biggest challenges in heat transfer. Despite numerous scientific investigations, prediction and prevention of fouling remain unresolved issues in process engineering and are responsible for large economic losses and environmental damage. This review article focuses specifically on crystallization fouling, providing a comprehensive overview of the state-of-the-art of fouling in heat exchangers. The fundamentals of the topic are discussed, as the term fouling resistance is introduced along with distinct fouling behaviour, observed in laboratory and industrial environments. Insight into subsequent phases of the fouling process is provided, along with the accompanying microscale events. Furthermore, the effects of fluid composition, temperature, flow velocity, surface condition, nucleate boiling and composite fouling are comprehensively discussed. Fouling modelling is systematically reviewed, from the early work of Kern and Seaton to recently used artificial neural networks and computational fluid dynamics. Finally, the most common fouling mitigation approaches are presented, including design considerations and various on-line strategies, as well as off-line cleaning. According to our review, several topics require further study, such as the initial stage of crystal formation, the effects of ageing, the interplay of two or more fouling mechanisms and the underlying phenomena of several mitigation strategies. heat exchanger fouling energy efficiency crystallization fouling modelling fouling mitigation prenosniki toplote mešanje energijska učinkovitost kristalizacija modeliranje mešanja preprečevanje mešanja true false true Angleški jezik Slovenski jezik Članek v reviji 2021-08-09 12:28:05 2021-08-09 12:28:15 2023-11-29 09:19:40 0000-00-00 00:00:00 2021 0 0 24 str. iss. 8, art. 1356 Vol. 9 Aug. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536.24:532.78 2227-9717 10.3390/pr9081356 72562947 RAZ_Berce_Jure_2021.pdf RAZ_Berce_Jure_2021.pdf 1 C699DBC0E24565658114B4CE369ACF6C b5e0ea6cc9760ee42e675196510c49cf0adda9f14da9f6612e02d50d0ded3e5b 54a64f79-f8fd-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145775 https://www.mdpi.com/2227-9717/9/8/1356 1 51dc581c-f8fc-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=145774 Fakulteta za strojništvo 0 0 0
