On the design criteria for the evaporated water flow rate in a wet air cooler
Description
The author discusses Poppe's formulation used for the modelling of heat exchangers between air and water, in Electricite de France's TEFERI numerical wet atmospheric cooler model: heat transfer laws in unsaturated and saturated air, Bosnjakivic's formula, evaporation coefficient. The theorical results show good agreement with the measurements taken on Neurath's cooler C in West Germany, whatever the ambient temperature (evaporated water flow rate, condensate content of warm air). The author then demonstrates the inadequacy of Merkel's method for calculating evaporated water flow rates, and estimates the influence of the assumptions made on the total error
Abstract (French)
L'auteur presente la formulation de Poppe utilisee pour la modelisation des echanges entre l'air et l'eau, dans le modele numerique de refrigerant atmospherique humide TEFERI d'Electricite de France: lois d'echange en air non sature et en air sature, formule de Bosnjakovic, coefficient d'evaporation. Les resultats theoriques sont en bon accord avec ceux des mesures realisees sur le refrigerant C de Neurath en Allemagne Federale, quelle que soit la temperature ambiante (debit d'eau evaporee, teneur en condensat de l'air chaud). Puis l'auteur montre l'insuffisance de la methode de Merkel pour le calcul des debits d'eau evaporee et evalue l'incidence des hypotheses faites sur l'erreur globaleAdditional details
