Mineral fouling control by underwater plasma discharge in a heat exchanger / Yang, Yong in Journal of heat transfer, Vol. 133 N° 5 (Mai 2011) 

Public ISBD [article]  in Journal of heat transfer > Vol. 133 N° 5 (Mai 2011) . - pp. [054502/1-4] Titre : Mineral fouling control by underwater plasma discharge in a heat exchanger Type de document : texte imprimé Auteurs : Yang, Yong, Auteur ; Hyoungsup Kim, Auteur ; Alexander Fridman, Auteur Année de publication : 2011 Article en page(s) : pp. [054502/1-4] Note générale : Physique Langues : Anglais (eng) Mots-clés : Physical  water  treatment  Plasma  Heat  exchanger  Mineral  fouling Index. décimale : 536 Chaleur. Thermodynamique Résumé : The excessive mineral contents in water circulation systems could cause severe fouling in heat transfer equipment. The present study investigated the effect of underwater pulsed spark discharges on the mitigation of mineral fouling in a concentric counterflow heat exchanger. Artificial hard water with calcium carbonate hardness of 250 mg/L was used with velocity ranging from 0.1 m/s to 0.5 m/s and zero blowdown. Fouling resistances decreased by 50–72% for the plasma treated cases compared with the values for no-treatment cases, indicating that the pulsed spark discharge could significantly mitigate the mineral fouling on the heat exchanger surface.
