Growth of dry patches in an evaporating film flowing around a horizontal circular tube

Modelling of a falling-film evaporator for adsorption chillers

“…result of a lower 𝑓𝑓 𝑤𝑤𝑤𝑤𝑤𝑤 with the increase of 𝑇𝑇 𝑟𝑟𝑤𝑤𝑟𝑟,𝑠𝑠𝑠𝑠𝑤𝑤 was also seen in literature(Bustamante et al (2020b);He et al (2021);Zhao et al (2022);LYu et al (2018)). …”

“…Yang et al (2017) obtained in their simulation that the falling-film evaporation performance worsened as the dry patches increased. He et al (2021) presented a mathematical model for the prediction of dry patches on falling-film considering the evaporation of film from the tube's surface. They obtained that the increase of film flow rate delayed the formation of dry patches, and that they appeared earlier in the surface with the increase of the spray temperature.…”
