TL;DR: In this paper, the effect of flow velocity on an electronic-antifouling (EAF) treatment, which was considered to mitigate mineral fouling in a heat exchanger with cooling tower water, was investigated.

TL;DR: In this paper, the authors investigated the mechanism of physical water treatment through particle count analysis of the water sample with and without PWT technology and found that the total number of particles in the PWT-treated cases increased from 165-539% as compared with the no-treatment cases depending on the flow rate.

TL;DR: In this paper, a new temperature-dependent viscosity equation based on the Carreau model is introduced; this model takes into account the effects of shear-thinning non-Newtonian characteristics and temperature on the viscosities of the polyacrylamide solution.

TL;DR: In this paper, an experimental study on the efficacy of a new physical water treatment technology using an oscillating electric field to mitigate mineral fouling in heat exchangers is presented. But the results at a cold-water side velocity of 0.3 m/s showed a 16-60% drop in fouling resistances from the baseline test, depending on the frequency of the electric field for the physical treatment-treated cases.

TL;DR: In this article, the feasibility of using electronic anti-fouling (EAF) technology to control precipitation fouling in a spirally-ribbed tube commonly used in chillers was investigated.
