含气溶胶竖直壁面冷凝液演化特性
Evolution characteristics of condensate on the vertical wall containing aerosols deposition
摘要
Abstract
In this study,we investigated the steam condensation process on a vertical wall of insoluble aerosol depo-sition to examine the influence of aerosol particle layer on the formation behavior of steam condensate.We conduc-ted a visual experimental study on a steam condensation platform to observe the evolution law of condensate,giving the effects of condensation rate and particle deposition density on the evolution characteristics of condensate.The results show that the evolution of condensate on the vertical wall undergoes droplet growth,droplet sliding,and the development of rivulets.The distribution of steady-state condensate includes three regions:rivulets,droplets,and thin water film.In an environment with a high condensation rate or particle deposition density,the droplet growth time is shorter,and the condensate evolution speed is faster.Furthermore,the number and coverage of rivulets in-crease as the condensation rate and deposition density increase.Moreover,this study provides a basis for optimizing the aerosol wash-down model.关键词
