摘要
为了有效地达到烘干辣椒的效果,建立了辣椒烘干箱的三维计算流体力学模型和基于CFD分析的辣椒烘干箱的结构优化模型,并对辣椒烘干箱内空气的流场进行了模拟。然后,根据模拟的结果进行多参数的结构优化,得出较为合理的结构和参数,即入口角度在60°情况下,前后挡板高度为34cm时,上间隙为10cm前凸形挡板效果最佳。
To effectively achieve the effect of drying peppers , the three-dimensional computational fluid dynamics model of peppers drying box and structural optimization model of peppers dryer based on CFD analysis are established .The flow field of pepper dryer is investigated by simulation .Then optimize the structure of multi-parameters based on the simula-tion results, and then achieve the more reasonable structure and parameters .the entrance angle at 60°, the height of front and back baffle in 34cm, the gap in 10cm, the umbonate baffle effect is the best .
