Abstract
Plate heat exchangers (PHEs) are widely used in chemical plants for cooling, and their performance typically deteriorates due to fouling formation. To address the operational lifetime of PHEs under fouling conditions and determine optimal repair time, a virtual framework is required to function as a digital twin. This study investigates the application of a vinyl acetate copolymer nano-coating on PHEs to reduce the fouling thickness of CaCO3 using a Multiphysics simulation approach. The novelty of this work lies in the development of a numerical framework capable of accurately forecasting optimal repair times before the system's efficiency declines. The results reveal that nanocoating reduces the thermal resistance and the fouling thickness by 65.77% and 58.8%, respectively, compared to the uncoated sample. The proposed framework accurately determines the thermodynamic behaviour of the PHE as a digital twin and predicts the appropriate time for its repair or replacement.
期刊介绍：
Biofouling is an international, peer-reviewed, multi-discliplinary journal which publishes original articles and mini-reviews and provides a forum for publication of pure and applied work on protein, microbial, fungal, plant and animal fouling and its control, as well as studies of all kinds on biofilms and bioadhesion.
Papers may be based on studies relating to characterisation, attachment, growth and control on any natural (living) or man-made surface in the freshwater, marine or aerial environments, including fouling, biofilms and bioadhesion in the medical, dental, and industrial context.
Specific areas of interest include antifouling technologies and coatings including transmission of invasive species, antimicrobial agents, biological interfaces, biomaterials, microbiologically influenced corrosion, membrane biofouling, food industry biofilms, biofilm based diseases and indwelling biomedical devices as substrata for fouling and biofilm growth, including papers based on clinically-relevant work using models that mimic the realistic environment in which they are intended to be used.
