摘要
以自行设计的0.4 m2薄膜蒸发器为模拟对象,采用CFD分析软件CFX4.4探讨刮板与筒壁间隙、刮板数、筒体长径比等结构参数对薄膜蒸发器内不同粘性料液的蒸发段长度(有效蒸发面积)和加热段膜内给热系数的影响,研究结果初步为薄膜蒸发器优化参数设计奠定基础。
Based on the designed 0. 4 m^2 thin film evaporator,the influence of the structure parameters such as the clearance between blade and wall, number of blade, length-diameter ratio on the evaporation length (effective evaporation area) and the heating section film heat transfer coef- ficient was discussed using the CFD software CFX4.4 with different viscous liquid as feed liquid, which primarily laid a foundation for optimization design of thin film evaporator.
