30. Proposta e comparação de um modelo fenomenológico com base em alto transporte de massa e supersaturação para torre de resfriamento de água. / Presentation and comparison of a model based in high mass transfer and supersaturation in a cooling water tower.
Cooling towers are equipment widely used in industrial plants, where these operate under severe conditions such as cooling water inlet temperatures above 50oC. Under this condition, there are high evaporation of water and high mass transfer, generally not considered in performance analysis of a cooling tower. This work presents and analyzes the differences b
