Comparaison du transfert de chaleur dans les conditions humides ou sèches et mesures de pertes de pression effectuées sur des matelas dispersants ondulés en PVC dans les tours de refroidissement.

Résumé

The paper presents the results of an experimental investigation of the performance of a cooling tower with PVC packing. The following were examined: the effect of surface roughness, the effect of the angle of roughness and the effect of packing spacing. The investigation was divided into two parts: comparison of film heat transfer with air pressure drop, without water circulation and comparison of enthalpy change and pressure drop in the model cooling tower, with circulation of water. Seven commercial packings were investigated and a discussion of the dimensionless correlation resulting is given.
