Model-Based Evaluation of Air-Side Fouling in Closed-Circuit Cooling Towers

Energies, 2021
Fouling is a permanent problem in process technology and is estimated to cost 0.25% of the gross national product. Evaporative cooling systems are especially susceptible to air-side fouling: as they work with untreated outside air, they are exposed to ...
