薄膜蒸发器结构参数对流体传热性能的影响
Influence of Structure Parameters of Thin Film Evaporator on the Fluid Heat Transfer Performance
【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。
【Abstract】 Based on the designed 0.4 m2 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 coefficient 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.
