Article Synopsis
  • This research presents an AI model that optimizes energy supply, biocide dosing, and maintenance for heat exchangers, taking into account various environmental and economic factors.
  • The study finds that biofilm leads to a significant drop in thermal efficiency (41%) and increases flow resistance (113%), resulting in a 9% rise in pump power consumption.
  • The AI model identifies day 44 as the optimal time to start biocide dosing, helping to maintain heat exchanger performance while minimizing environmental impact from industrial operations.*

A novel efficiency reduction model to tubular heat exchanger based on heat transfer losses by biofilm adhesion is proposed, which included a modified equation based on the real data-dependent time, seawater, hydrodynamics and heat transfer resistance using computational fluid dynamics (CFD). The biofilm growth model based on Verhulst model and experimental data has been obtained and simulated in a CFD software tool to analyze the tubular heat exchanger performance prediction cooled by seawater. The biofilm CFD model with appropriate fit, and the correlation coefficient (R2) values are between 0.

A CUSUM chart method is presented as an alternative tool for continuous monitoring of an electromagnetic field-based (EMF) antifouling (AF) treatment of a heat exchanger cooled by seawater. During an initial experimental phase, biofilm growth was allowed in a heat exchanger formed of four tubes until sufficient growth had been established. In two of the tubes, continuous EMF treatment was then applied.
