摘要
本文利用经改造过的KIVAII程序 ,采用非正交贴体网格方法对螺旋流排气系统始端模件的流场进行了三维稳态计算。并与利用三维粒子动态分析仪 (PDA)对其进行准三维测量的结果相比较 ,计算结果与试验结果基本吻合 ,说明对程序的改造是成功的 。
Three dimensional flow calculations on steady turbulent flow field in closed end T junction of swirl flow exhaust system are performed with non orthogonal body fitted mesh on the basis of revised KIVA II code.3D PDA is introduced to measure the quasi three dimensional measurement on the experimental module piece and the comparisons between calculated and measured ones show a good agreement,which indicates validity of revised code and reveals pattern of the T junction flow field.
