基于Fluent的负压式电加热干燥机内部流场分析与机构参数优化
Analysis of internal flow field and optimization of mechanism parameters of negative pressure electric heating dryer based on fluent
摘要
Abstract
The problems of uneven flow field and low drying efficiency in the negative pressure electric heating dryer were found and supposed to solve in this study.Based on Fluent,numerical simulation of wind velocity field and temperature field in negative pressure electric heating dryer was carried out.And by using the improved design of SolidWorks internal structure of the dryer,the main factors influencing the drying efficiency of the working parameter and structure parameter were tested.By using changing the working parameters and optimize the structure,the internal flow field uniformity of the optimal effect of dryer were achieved.The results showed that the Solid-Works optimization design of dryer internal flow field uniformity was obviously improved compared with the original structure,and the optimized structure parameters could meet the design requirements.Therefore,this method greatly improved the work efficiency of heat utilization of dryer.关键词
