摘  要:为改善拉幅定型机烘箱内风道的气流分布和喷嘴出口速度不均匀的现象,采用Fluent 14.5软件对风道的流场和压力场进行数值模拟,分析风道的速度矢量图,计算不同位置喷嘴的出口速度.模拟计算结果表明:在风道内等间距安装5块倾斜角为4°的导流板,并调整风道锥角为3°时,可以很大程度改善风道内气流分布和喷嘴出口速度的均匀性,结构优化也较为合理可行.In order to decrease uneven distribution of airflow and nozzle outlet velocity for air duct in stenter oven,velocity field and pressure field of the air duct were numerically calculated by the Fluent 14.5.Moreover,velocity vector graph and outlet velocity of the nozzle in different positions for the air duct were also analyzed.Finally,the numerical simulation indicated that installing five guide plates with 4° title angle in the air duct by same spaced and adjusting taper angle of the air duct to 3°,which could greatly improved distribution of the airflow and the nozzle outlet velocity and make structural optimization more reasonable and feasible.
